Jedikiah takes Kenny back to his base, and imprisons him, Ginge and Lefty in a room containing a matter transmitter, which transports them all to a spaceship. Carol, John and Stephen locate Jedikiah's base but only just escape before it explodes. Jedikiah reveals that he is a shape-changing android, working for an alien creature known as the Cyclops. The Cyclops contacts Carol, John and Stephen, telling them to come to his spaceship if they want Kenny back.
John and Stephen jaunt to the ship but are caught in a trap. Carol jaunts to a different part of the ship, and manages to damage Jedikiah with a stun gun. The ship is damaged, releasing John and Stephen. They then find Kenny, and a reformed Ginge and Lefty and release them. The Cyclops explains that his crew has been killed and he needs telepaths to pilot the ship home. As the vessel breaks up, the Cyclops is killed, and the Tomorrow People jaunt back to Earth just before the ship explodes. Jedikiah is left floating in space.
The Tomorrow People - John, Carol and Kenny - have discovered that a teenager called Stephen is about to manifest his powers. They trace him to hospital, where he was taken after collapsing from the shock of his new abilities. Carol teleports into his room to make contact, and begins to teach Stephen how to control his telepathy. They are attacked by Ginge and Lefty, two bikers acting under instruction from the mysterious Jedikiah.
John, Carol and Kenny mount an operation to rescue the kidnapped Stephen. They take him to their Lab, based in a disused part of the London Underground train system, and introduce him to TIM, their biotropic sentient computer. Stephen is still under Jedikiah�s control, and, left alone in the Lab, he deactivates TIM's external connections and opens the door to allow Jedikiah, Ginge and Lefty to enter.
Carol realises that TIM has stopped working and contacts John. They both go to the Lab, but are caught in a trap set by Jedikiah and are stranded in hyperspace. Kenny jaunts to the Lab and manages to reactivate TIM, but Jedikiah burns through the lock of the door, and Kenny is captured. TIM locates Carol and John in hyperspace and jaunts them back to the Lab, but Jedikiah uses a device to paralyse them all.
Five hundred years in the future, a spaceship comes across the shape-changing robot Jedikiah, floating in space. The captain, Rabowski, repairs it. In the present day, Stephen is trying unsuccessfully to develop a photograph of something he saw in hyperspace. Carol and Stephen jaunt into hyperspace to see if they can locate anything unusual. Back on the spaceship, Robowski shows Jedikiah his captive, Peter, whose telepathic abilities are being negated by an alien creature known as a Medusa. Jedikiah tricks Peter into operating Rabowski's Time Key, and they travel back to the Tower of London in the present day, and steal the Crown Jewels. When Carol and Stephen jaunt back to the Lab, they find that everyone is frozen.
Carol and Stephen find Jedikiah, Rabowski and Peter at the Tower of London, but Carol is kidnapped and taken back to Rabowski�s spaceship in the future. Jedikiah and Rabowski put Carol into the airlock and start pumping the air out, to force Peter to operate the Time Key again.
Peter agrees to use the Time Key to save Carol, but insists that he be able to use his telepathy to help in the task. Jedikiah lets him, and Peter manages to contact John, Kenny and Stephen, telling them where he and Carol being held. John and Stephen jaunt into hyperspace to look for the spaceship, while Rabowski, Jedikiah and the Medusa use the Time Key to go to the underground tunnels near the Lab. Rabowski captures Ginge, but the biker manages to push the Medusa onto the electrified rail lines, killing it. Ginge is then taken back to the spaceship. John and Stephen find the spaceship in hyperspace, but are shot by the ship�s laser.
TIM brings John and Stephen back to the Lab and, with Kenny, is able to bring them back to life. Jedikiah turns against Rabowski and, in the struggle, the Time Key is damaged. Rabowski makes his way to where Carol, Peter and Ginge are imprisoned, and Jedikiah turns the air and heat off. John and Stephen wake up, have to sleep to regain their strength. Jedikiah restores life support, locks up Rabowski and takes Peter to repair the Time Key. But Peter booby-traps the Time Key, and releases Carol and Rabowski from their cages. Attempting to escape, Jedikiah and Rabowski fight, but are transported by the Time Key to the surface of Mercury. Peter then uses the Time Key to return everyone to their own time zones.
The Tomorrow People are worried by the dramatic increase in natural disasters on Earth. Ginge and Lefty are in Clacton-on-Sea. Ginge meets a girl named Joy, who runs a Haunted House with a man called Smithers. Ginge is kidnapped by Joy, who is working for a strange hooded figure known as the Spidron. Using a matter transporter, Ginge is transported to Spidron�s lair, where he is brainwashed and put to work mining for valuable minerals.
Lefty is worried about Ginge, and contacts the Tomorrow People. Stephen goes with him to the amusement arcade, where they discover the matter transporter in the Haunted House. They are seen by Smithers and Joy. Lefty escapes, but Stephen is captured by Joy and thrown into the sea. John and Carol arrive, but the mysterious man has already rescued Stephen, and teleports Stephen away.
Carol and John go back to the Lab and find Stephen, unharmed. The mysterious man reveals himself to be Steen, a galactic policeman, who is chasing the criminal Spidron, who has been raiding planets for magnamite, a rare substance that holds planets together. Steen, Carol, John and Stephen use the matter transporter in the Haunted House to travel to Spidron's base. Spidron releases all his captives from mind control and opens the lava ducts to flood the base.
Ginge breaks free and closes the lava ducts, while Steen, Carol, John and Stephen find the Spidron's control room, just as he and Joy teleport away. Later, Joy goes to Spidron's hideout near his spaceship, and they prepare to leave Earth with the magnamite. Steen, Carol, John and Stephen track Spidron's spaceship to London, where they find a sewer entrance. Spidron uses mind control on Ginge and Lefty, and escapes alone in his spaceship. Steen arrests Joy, who reveals that she double-crossed Spidron by keeping the magnamite on Earth in the mining areas. When the lava reached the storage areas, the magnamite flowed back into the Earth's crust, stabilising it and averting the destruction of the planet.
John and Stephen hear Elizabeth's cries and jaunt to help, scaring the boys away. Stephen returns to the school and finds the video camera smashed, while John buys the painting from the junk shop, and discovers that Robert lives above the shop. Stephen is invited home by Robert, who shows him a cellar full of strange pictures, and boxes of blue and green badges; he tells Stephen that he did not know his parents, and that his grandfather is not really his grandfather. He also gives Stephen another picture. Meanwhile, John and Tim attempt a Neutron examination on their painting, but it destroys itself. Tim discovers that Robert does not appear in official records. Robert has been using the picture he gave to Stephen to spy on the Tomorrow People in the Lab, and when John returns to the shop, he is captured by Robert�s grandfather. Under Robert�s control, John telekinetically damages the Lab, then disappears.
But Chris escapes, locking the policemen and Robert's grandfather in the cellar. Robert reveals to John that he is an alien Denagelee, but was born on Earth from an egg. When hatching, his species require aggressive energy to complete the transformation; the destruction of the Roman Empire was caused when his mother hatched - this time there will be many thousand of his race hatching. John persuades Robert to release him, so that the Tomorrow People can try to find a safe way for the aliens to hatch. As the hatching begins, Stephen suggests that if they could use a giant stun gun in space to put everyone to sleep - their REM state could provide the energy needed by the Denagelee, without hurting anyone. John, Stephen and Elizabeth collect the parts needed for the gun, and take them to the Watchdog satellite to assemble. Once activated, the stun gun sends everyone to sleep, allowing them to dream the violence the Denagelee require. The aliens leave Earth, agreeing never to return. John, Stephen and Elizabeth return home, and Stephen erases the memories of the policemen, who set Chris free.
Stephen�s classmate, Robert, paints an accurate picture of Rexal 4, an alien world. Recognising it from his travels, Stephen tells John and Tim, and mentions that he thinks his teacher, Elizabeth, is breaking-out. The following day, Elizabeth witnesses Stephen in the act of jaunting home and hears him telepathically talking to John and Tim, but is convinced that it is a trick. The next day Robert's picture 4 has changed from a bright, sunny landscape to a dark and stormy picture. Investigating back at the Lab, John and Tim find similar instances of pictures that change, causing serious disturbances amongst schoolchildren. Stephen witnesses aggressive behaviour amongst his schoolmates. He takes John to meet Elizabeth, but she refuses to believe him and tries to leave, but as John jaunts in front of her to stop her, it triggers her breaking-out. She tries to run away again, but Stephen jaunts right in front of her. She panics and jaunts away, out of control.
John and Stephen jaunt into hyperspace to look for Elizabeth. When they find her she jaunts back to the classroom. Stephen and John manage to calm her down, and take her to the Lab. The next day sees Robert hand out blue and green badges; Elizabeth takes a blue one, while Stephen takes green. Chris arrives at the Lab after a fight with his brother Ginge; he tells John that the fight was due to Chris being is a Green and Ginge a Blue. John removes Chris's badge, returning him to normal. Back at school a fight breaks out in the school classroom, with even Stephen and Elizabeth taking part. That night John and Stephen return to the classroom and set up a video camera to try to record the picture changing. Meanwhile, Elizabeth passes a junk shop and sees another of the strange pictures in the window. As the picture changes, she is threatened by a group of boys.
John returns to the cellar, where his powers are negated. Stephen attempts to rescue John, but his stun gun has no effect on Robert, and he is forced to flee. Chris and two friends also mount an unsuccessful attempt. Chris later follows the mysterious boy, but is warned off by a policeman. However he manages to retrieve some books, including volume four of �The Decline and Fall of the Roman Empire�, which Robert has dropped. Taking them to the Lab, Chris shows Tim, who realises that the Roman Empire also broke into two factions: blue and green. Robert instructs his grandfather to tell the police that he has gone missing, then leaves with John. Attempting to help Elizabeth at the school, Chris is instead caught by the police, who charge him with Robert's disappearance, and take him to the shop to look for the boy. When they get to the cellar, all of the pictures have gone, as has John.
John and Stephen both share strange dreams of Peter, the Time Guardian, running through a forest, and showing them a vase. The two of them look through thousands of pictures of vases, eventually finding Peter�s, which is owned by Professor Cawston, and looked after by Professor Garner. Stephen tricks Professor Gamer into bringing the vase to him. He grabs its lid, and jaunts back to the Lab with it. The lid has strange markings which are designs for a Neutron Interton. The Tomorrow People build the device: a small disc. Nothing happens when Chris and Elizabeth pick it up, but when Stephen picks it up he disappears.
Stephen is caught in a time trap. While John attempts to make another Time Disc, Stephen meets a Guardian of Time called Zenon, Peter's grandfather. He frees Stephen and warns him not to build another Time Disc, as its user could be lost in eternity; Peter is trapped in Roman times, and Zenon gives Stephen five Time Discs so that the Tomorrow People can try to rescue him. Stephen arrives in the Lab just in time to stop John using his new Time Disc. Later, Professor Garner tells them that the vase came from a gladiator school in Silchester, run by a ruthless man named Gaius. John, Stephen, Elizabeth and Chris use the Discs return to ancient Roman Britain. They �sell� Stephen to the gladiator school, but then discover that their telepathic abilities have disappeared. Stephen is locked in a dungeon with Peter, who thinks that someone is transmitting a telepathy-inhibiting radiation. After Gaius selects Stephen to be tested by fighting, John, Elizabeth and Chris try to buy him back, but Gaius refuses; Elizabeth thinks Gaius knows they are telepaths. Stephen is defeated in combat.
Gaius spares Stephen's life. Stephen meets Cotus, another trainee who is due to be killed in horse trials. That night John, Elizabeth and Chris break into the gladiator school, where they hear a steam engine, sixteen-hundred years before it should have been invented. Peter suspects that Gaius is responsible for the time warp. Chris manages to free Stephen, Peter and Cotus, and Peter attempts to arrest Gaius, but he escapes in a Time Pump. The trainee gladiators are released just before the Time Pump explodes, and the Tomorrow People return to the Twentieth Century. But the Lab is not there, instead, they are in a futuristic base populated by ape-like creatures. Cotus returns to the gladiator school and begins to repair the steam engine.
John, Stephen, Elizabeth and Chris discover that the Roman Empire never ended. The Romans developed advanced technology, which enabled them to rule the world, aided by their ape-servants from the planet Trista. John, Stephen, Elizabeth and Chris return to ancient Britain, but their conversation has been overheard by Gaius, who follows them to the gladiator school. They destroy the remains of the steam engine, but they and Cotus are all captured by Gaius. Cotus tries to stop them from being killed, and is knocked-out by one of Gaius' guards. Cotus loses his memory, and Gaius and his guards all disappear. Time has been restored to its correct path.
Stephen, who was a schoolboy fencing champion, is able to disarm the boys. He is told that Operation Silver Thread is to happen the next day, and is to involve the Damocles space-station. One of the crew of the Damocles, Lee Wan, has an accident whilst working outside the space-station, and is blasted into space. John, Stephen and Elizabeth use a matter transporter to take Chris's transit van into space. They rescue Lee Wan, and take him back to the Lab. Stephen returns to the school, and that night is initiated into the Doomsday Men. Operation Silver Thread begins: General McLelland and his troops arrive at the Damocles in a space ship. Pretending to be the relief crew, they seize control of the station.
John, Stephen and Elizabeth decide to try to re-capture the Damocles. Lee Wan tells them of a dead man's switch that can launch nuclear missiles held aboard the station. John takes Lee Wan's space suit, and floats past the Damocles, pretending to be the dead astronaut. Looking through an observation port, he sees that the dead man�s switch is in use. The Doomsday Men transmit their demands to the United Nations, who postpone the signing of the peace treaty. Meanwhile, Stephen and the boys at the school go on a cross-country run. While Tim matches the voice from the Damocles with that of General McLelland, Stephen sees Douglas being kidnapped. He tries to help, but is knocked unconscious.
Stephen is found by his classmates, and taken back to the school. Douglas has willingly gone with the kidnappers to an old deserted windmill, and when one of the teachers, Dr. Laird takes some spare clothes to him, Stephen and Paul, one of the schoolboys, hide in the back of his car. But Dr. Laird captures them, and is about to shoot them when Stephen activates his jaunting belt, taking Paul and Douglas back to the Lab with him. Tim re-educates the two boys, showing them how terrible war actually is, and they decide to help. Dressed in Lee Wan's space suit, John drifts up to the space-station, and sees General McLelland at the dead man's switch. Douglas, Stephen and Lee Wan jaunt into the space-station, but in the confrontation, the General lets go of the handle. They are unable to stop the commencement of the launch countdown, but Douglas throws his bagpipes into the artificial gravity machinery that makes the living quarters rotate, causing the whole station to spin. The missiles fire harmlessly into the sun.
Stephen goes under-cover to investigate a military organisation called the "Doomsday Men". The leader�s grandson attends Glen College, which Stephen discovers is a training ground for Doomsday Men, and that its head, General McLelland, is planning a suicide mission. After Stephen is asked to join the organisation by Douglas, he discovers that the mission, "Operation Silver Thread", is to prevent the signing of a peace treaty. Stephen is summoned to the gym, where he has to fight several boys with a sabre.
Prof. Cawston discovers that a gypsy boy named Tyso is about to break-out, and arranges to show him to the military. While attempting to contact Tyso, Stephen sees through his eyes, and recognises Cawston. He jaunts to the professor's office, but he refuses to help. Later, at the demonstration, Tyso�s powers are watched by Col. Masters and Tricia Conway. Prof. Cawston subsequently contacts the Tomorrow People, telling them that Tyso had disappeared. John, Stephen and Elizabeth jaunt to Tyso's caravan, where they are told by Tyso�s mother that his father had sold him to Col. Masters. The trio then arrive at Cawston's office, where the professor tells them that the colonel wanted him to join his research group. However, Trish, a telepath, has read the professor's mind and warned Masters about Stephen and Elizabeth. John realises that they must find Tyso within two to three days, otherwise the strain of breaking-out will kill him.
Prof. Cawston arranges for Stephen to demonstrate his abilities to Col. Masters and Tricia, but the latter is aware that Stephen is deliberately making mistakes. Stephen goes undercover at a hostel planning to allow Col. Masters to kidnap him. Despite knowing that it is a set-up, Tricia and Masters take the Stephen, injecting him with a drug to render him unconscious, and the professor. Back at the research centre, Prof. Cawston is shown Tyso and Stephen connected to life support machines and drugged by Synaptol. The professor is tasked with reviving them, while preventing them from jaunting. Tricia takes an unconscious Prof. Cawston back to his office, planting bugs and a video camera on him before he awakes. The professor comes to and calls John and Elizabeth, telling them that he has found Stephen and Tyso.
Elizabeth jaunts to Prof. Cawston's office, watched by Col. Masters and Tricia. She gives the professor a ring with a homing device in it, but he is kidnapped by Masters before he can use it. When John and Elizabeth investigate, they narrowly escape an explosion, as the colonel has set the ring to self-destruct. Cawston is hypnotised and interrogated by the colonel, and reveals information about the Tomorrow People. Col. Masters wakes Tyso and tells him to contact the Tomorrow People telepathically. John and Elizabeth arrive at Col. Master's office in the Experimental Weapons Establishment, and stun him and Tricia. Cawston shows them where the antidote for the Synaptrol is, but Tricia comes round and hits them all with the drug. John manages to jaunt to the Lab, but then collapses. Col. Masters revives Elizabeth, and tells her to help them or Stephen and Tyso will die.
Chris arrives at the Lab and uses the antidote to revive John. While Elizabeth is forced to demonstrate her powers to Col. Masters and Tricia, John and Chris kidnap the Prime Minister and take him back to the Lab. Elizabeth is told by Masters to jaunt to Moscow and buy a Russian doll. Doing so, she jaunts to the Lab, where John opens the doll to find a mind control device. The Prime Minister destroys the device, and Elizabeth returns to Master's office. When he discovers that the device is missing, Masters threatens to turn off the life support machines, but he receives a phone call ordering him to release all the Tomorrow People. Tyso begins to break-out, and is taken to the Lab. John tells Tricia that she is a potential Tomorrow Person, and that it isn�t too late for her to join them.
Ambassador Timus Irnok Mosta visits the Tomorrow People in their Lab, and asks for their help. He takes John and Elizabeth to the Great Pyramid of Chaeops in Egypt, and tells them that the pyramids were built by the alien Kulthan. Hidden behind a secret panel is a Psi-Damping transmitter, used to prevent telepathic abilities operating on Earth. Timus asks the Tomorrow People to travel the planet Peeri, to deactivate the Psi Damping Transmitter there, and to persuade the Kulthan to leave. Unlike standard Galactic Agents, the Tomorrow People are not reliant on their telepathic powers, and are perfect for the mission. Arriving on Peerri, John, Stephen, Elizabeth and Tyso set up base in a cave used by Tikno, one of Mosta�s clone brothers. They rescue a girl, Lenda, from a hunt, but Tyso gets his foot stuck in a man-trap, and some hunters approach.
Tyso is about to be caught by the hunters, when a Kulthan appears and frightens them away, enabling Tyso to escape. Stephen finds Tyso and carries him back to the hideout, but the Kulthan reappears. Stephen stuns the creatures with his stun-gun, but they discover that the Kulthan is Tikno in disguise. Tikno explains that the hunt is to capture Vesh, and is organised by the Veshtaker. When captured, the Vesh are burned on top of high towers, and the Kulthan then use a matter transporter to take the Vesh to their space-station. John, Stephen and Tikno set off for the pyramid where the Psi-Damping Transmitter is located, but are followed by Arkron, a Vesh Warrior. Arkron returns with Vanyon, his leader, and other warriors, and they shoot John, Stephen and Tikno with crossbows.
John, Stephen and Tikno regain consciousness as the Vesh Warriors return, and Tikno convinces Vanyon that they are friendly and want to defeat the Kulthan. They decide to join forces and attack the Kulthan pyramid. Stephen and Arkron return to the hideout to tell Elizabeth what is happening, but find that everyone has been captured by the Veshtaker. As John, Tikno and the Vesh Warriors approach the pyramid they feel the effect of the Psi-Damping Transmitter, and hear a humming sound. The Veshtaker take Elizabeth, Tyso and Lenda to the top of the tallest tower, so that they can be scarificed. Stephen and Arkron journey to the Veshtaker's castle, but are captured before they can mount a rescue. John, Tikno and the Vesh Warriors attack the pyramid, while Stephen and Arkron are thrown into the dungeon. John and Tikno enter the secret passage in the pyramid, and John manages to destroy the Psi-Damping Transmitter, enabling Elizabeth, Tyso and Lenda to escape from the burning, and Stephen and Arkron to escape from the dungeon.
John and Stephen jaunt back to the Lab as the police arrive. Elizabeth tells the Momma that Elmer has been put in jail, and she talks to the Ship; it tells her that if Elmer is not returned within one day the Earth will be destroyed. Elizabeth returns to the Lab, where John formulates a plan to break Elmer out of the police station. Tyso takes some bees into the police station, and everyone flees, enabling them to release Elmer. Elizabeth and Stephen take him to where they think the doozlum pin might be, but Stephen accidentally steps on it, and is transported back to the ship. He jaunts back to Earth with the doozlum pin, which Elmer uses, and then he and Elizabeth return to the Lab. John jaunts to the Ship to check that Elmer has got back safely, but Emily takes a liking to him, and he only just escapes. The Momma sends Elmer back to Earth, he instead goes to the pub and is arrested. The Momma contacts the Tomorrow People, demanding that they return Elmer, or the Earth would be destroyed.
John contacts the Prime Minister, who authorises Elmer�s release. John takes Elmer to the doozlum pin, but Elmer refuses to go back to the ship, instead sending John. The Momma and Emily celebrate John's arrival, fitting him with Tickling Boots. Meanwhile, Elmer is re-arrested, and Elizabeth asks for his custody. The Ship tells John that he is to be the pair-mate for Emily, and that his telepathic powers have been blocked. Elmer arrives at the Lab, and tells Elizabeth that his people live on the Ship for many generations, and that when the next generation is been born, the Momma eats the father. On the Ship John is forced to wait on Emily, but when she leaves the room, he jams the waste disposal hatch open, allowing the air to escape; he then tells the ship to remove his tickling boots. The ship informs him that their original home planet was destroyed by nuclear weapons; the ship was made to allow some to escape and search for a new planet. It has decided that no planet is suitable, and the search must continue. John persuades the ship to switch-off as the search has been completed, and then he pilots it to Earth. The Momma becomes a fish shopkeeper, Emily a landlady in a pub, and Elmer a traffic warden.
A spaceship arrives in orbit around the Earth, containing the Momma, Emily and Elmer, members of a matriarchal society. Based on television signals, they believe that Earth is like a wild west film. Tim tracks the ship into orbit, and John and Elizabeth jaunt near to it to investigate. The Momma tells Elmer to go to Earth to get fresh food supplies. When the Ship stuns and captures Elizabeth, John jaunts back to the Lab. Elizabeth awakens, and is accepted as an equal by the Momma and Emily. On Earth, shoots a shopkeeper when he is collecting food. Tim intercepts police reports, and Stephen jaunts to the shop, using his telekinesis to heal the proprietor. Elmer finds a pub, treating it like a western saloon. Elizabeth discovers that Elmer must return to his place of arrival, where the doozlum pin is located; she also finds out that the Ship controls the people on board. John and Stephen jaunt to the pub, but are unable to transport Elmer away, and the police arrive.
Jedikiah, a shape-changing android believed to have been destroyed, was rescued and sent to ancient Egypt by an alien race. He was placed in a tomb and remained there for 500 years until it was reopened by Professor Cawston and Professor Johnston. Freed Jedikiah has one thing on his mind: revenge on the Tomorrow People.
Patricia Conway goes to Jedikiah thinking he is Stephen and asks him to go back to EWE and talk to Col. Masters about working for them. He agrees to go and kills Col. Masters leaving Patricia to think that Stephen has committed murder. She goes to see Professor Cawston to ask his help in finding Stephen. Meanwhile Jedikiah takes the shape of several different people including Patricia and Professor Cawston hoping they will lead him to the Tomorrow People. Liz and John are gunned down after jaunting in and surprising a EWE guard and placed in ICU.
Finding Stephen and Tyso, Jedikiah forces them to lead him back to the Lab. He switches TIM off and places silencer bands on Stephen and Tyso to stop them from using their powers. Meanwhile Patricia starts to break out and teleports to the Lab, where she turns TIM back on. TIM has enough time to call the Timus of the Galactic Trig to help save the day.
John and Stephen jaunt to the bank vault and discover that psychokinetic energy has been used; using their contact with the Prime Minister they arrange a meeting with Inspector Burke. Lord Dunning threatens Mike's family, but the boy uses his powers to frighten him off. After Two Tone and Slow are interrogated by John, the Tomorrow People visit O'Reilly, who tells them that Dunning has kidnapped Mike, his mother and sister. Burke takes John, Stephen and Elizabeth to Dunning's country house, but the Lord denies any knowledge of Mike. While Dunning and his heavies visit O'Reilly, Mike opens the lock on the cellar door, and he and his family escape. Mike manages to attract the attention of Burke, but he, his mother and sister are recaptured when Dunning and his butler Thwaites create a diversion. Burke calls Tim on the special telephone number and tells him of his sighting of Mike. He then organises a raid on Lord Dunning's house.
Mike, a new Tomorrow Person, uses his telekinesis to open a neighbour's door. Meanwhile, John, Stephen, Elizabeth and Tyso return from the Galactric Trig, arriving in a dusty and cobweb-covered Lab. Mike's neighbour, Mister O'Reilly, is visited by two heavies, Two Tone and Slow, who want money that O'Reilly owes from gambling at Lord Dunning's betting shops. Unable to pay, O'Reilly tells them about Mike's ability to open locks; he brings Mike to meet them, and they trick him into showing his power, and then blackmail him into helping them break into the National Victoria Bank. After opening the locks and overriding the alarm systems. Mike tricks the heavies, locking them in the vault. His laughter is heard telepathically by John, Elizabeth and Stephen, who decide not to contact him in order to reduce the problems of breaking-out. A police inspector, Burke, releases Two Tone and Slow, but they refuse to talk. The next day O'Reilly asks Mike to his flat, as Lord Dunning wants to meet him.
Mike hears the commotion, and tricks his guard into firing his gun, alerting the inspector, who releases them. John tells Mike and Burke that they cannot prosecute Dunning as it would draw attention to Mike's ability. Stephen teaches Mike how to jaunt, but Mike is still upset about Dunning, and goes to see him, offering to go into partnership with him. Stephen sees Mike getting out of Dunning's Rolls Royce, and brings him to the Lab, but he refuses to talk to the Tomorrow People, and jaunts away. However, John has planted a bugging device on the Rolls Royce. Mike arrives at the American Union bank, and opens the door, allowing Lord Dunning and Thwaites to enter. On a tip-off, Inspector Burke follows them in, and tries to arrest them, but Thwaites threatens to shoot Mike. But Mike jaunts, and the Inspector faints. Following the tracking signal, John, Stephen and Elizabeth jaunt to the vault and capture Lord Dunning and Thwaites. Mike joins the Tomorrow People.
When Tim detects a signal from a drifting shuttlecraft, John and Stephen investigate and find a young humanoid alien called Kwaan. They take him to the Lab, where he tells them that he left the Father-ship to get help from his home-world of Regiorra. Kwaan communicates with the planet�s ruler, Tirayaan, who sends power to the shuttlecraft. Mike, John, Stephen and Kwaan return to the shuttlecraft, but it has drifted too far off-course and Kwaan will be unable to return to Regoraa, and so he decides to return to the Father-ship, which is trapped near a hole in space. As they approach the Father-ship the Tomorrow People lose communication with Tim and Elizabeth, and are unable to jaunt due a force-field.
Elizabeth jaunts to the spaceship with a small box which acts as a connection to Tim, which they connect to the power system on the ship. Tim tells them that they cannot jaunt back to Earth until they find a solution to the force field, which may be on the father-ship. Arriving at the father-ship, they meet Tirayaan, who informs them that the ship will be dragged into the hole in two days, and that it has been seized by the rebellious Vektaan as part of a plot to take control of the homeworld. Vektaan captures the Tomorrow People, Kwaan and Tirayaan, but John and Stephen offer to help him save the father-ship, and, together with Tim, they work on the bridge controls. Tirayaan admits that he set the ship on its course, and John tells Vektaan that he will save the father-ship if all the prisoners are put onto the shuttlecraft, with enough power to get them back to Earth. Vektaan aggress and allows them to leave in the shuttlecraft. John returns control of the father-ship and jaunts to the shuttlecraft, but Tim's box is destroyed, and they realise that Vektaan has programmed the small ship to fly into the hole.
As the shuttlecraft enters the hole, the temperature inside begins to drop. Timus arrives at the Lab and boosts Tim's power, enabling him to locate the shuttlecraft in the hole, but the picture fades as the shuttle goes out of range, and Timus is recalled to the Galactic Federation to report. Another hole appears directly in front of the shuttlecraft, and the Tomorrow People notice that their watches have stopped, despite their being in the hole for seven or eight hours. The shuttlecraft slows down and the reactors begin working again.
As the shuttlecraft slows down and the reactors begin working again, they approach the hole and see stars. On the father-ship, Vektaan sees the shuttlecraft re-emerging from the hole. Tirayaan tells them that they have travelled in a circle, and that it has only been a few minutes since they entered the hole. Vektaan informs them that he has abandoned the rebellion, and wants them to return to the father-ship. But when Tirayaan tries to contact Vektaan, the Father-ship fires at the shuttle craft; one of the energy bolts enters the hole, and returns a few seconds later, destroying the father-ship. The Tomorrow People, Tirayaan and Kwaan return to Earth.
After an attack on the lab by the SIS, Mike tries to help a girl who may become a Tomorrow Person escape from the KGB.
John, Liz and Mike try to save the Russian girl from both the British SIS and the Russian KGB, with mixed success.
After the Death of Pavla, the Tomorrow People decide to go on Holiday, so Timus sends them to do an archeological dig on the planet Galia. There they run across two excaped slave boys.
With Mike a slave inside the alien's camp, the other Tomorrow People attempt to drive the alien slavers off Galia.
Jake tells John to stop Elizabeth telling anyone what happened, and gives him a knife. John jaunts back to the Lab and tries to kill Elizabeth, but his instinct not to kill breaks Jake's control. Mike and Jake go to the Hearts of Sogguth headquarters, but during a strange ceremony a voice warns Jake that Mike is different. Elizabeth finds an old book that predicts that Lord Sogguth will return when a million people hear the beat of his heart, and that he would destroy the Lords of the Heavens. Elizabeth thinks that the television broadcast will reach more than a million and the Lords of Heaven could be the Galactic Trig. The Hearts of Sogguth capture Mike, and something comes out of the sacred drum and takes control of him. When contacted telepathically by John and Elizabeth, Mike lies, saying that he is at home, and that the television programmed is the next day. John and Elizabeth jaunt to the Hearts of Sogguth headquarters to try to destroy the drum, but are discovered by Jake, who makes John attack Elizabeth. Jake tries to stab Elizabeth, but she jaunts back to the Lab. The next day Elizabeth jaunts to the television studio just before the broadcast; John tells Jake of her arrival, and persuaded Jake to let him stop her with a stun gun. Elizabeth is up on the gantry with a laser blaster, ready to destroy the drum, but is stopped by John before she can fire. Mike plays the drum in order to release Lord Sogguth, but Elizabeth manages to destroy the instrument. Sogguth is defeated, and, as he retreats back to the centre of the Earth, he takes Jake's soul with him, leaving behind just his skeleton.
After Mike's band, �The Fresh Hearts� plays at a gig, a man named Jake asks Elizabeth if he could become the band's manager. This offer excites the band, but Elizabeth thinks that Jake is a cheat and a fraud. At a rehearsal Jake asks Mike to play his drums to the special rhythm on a metronome, but the cleaner working in the room starts to act very strangely, and has to be taken outside to recover. Jake says it is their music that affected her, and arranges for music television producer Mike Harding to watch the band play that evening. Harding is impressed, and arranges for them to play live on television. Elizabeth discovers that Jake is actually Professor James Marsden, leader of a religious sect known as the Hearts of Sogguth. She persuades John of infiltrate the group, and he is initiated into them, but thinks they are harmless. Jake gives Mike the Heart of Sogguth drum to play, but warns him not to play the special rhythm. Elizabeth takes John to watch the Mike's band play at the disco, and they are introduced as the Hearts of Sogguth by Jake. Mike plays the drum to the special rhythm affecting everyone in the room except for Elizabeth. She jaunts onto the stage and stops Mike, but then finds that John is acting very strangely. Elizabeth jaunts back to the Lab, telling Tim that she thinks that John and Mike are under someone's control.
John lets Mike take his first solo glider flight, but while in the air a girl, Hsui Tai, contacts him telepathically, and he loses control of the glider. Just in time, John manages to jaunt inside the glider and regains control. Hsui Tai tells Matsu Tan, a Shansu monk, that she believes Mike to be the lost god Kishnu. After Tim is unable to find a reason for Mike's blackout, Elizabeth contacts John and Mike while on a mission for the Galactic Federation. Matsu Tan and the Sage discuss Hsui Tai's contact with Kishnu, and decide that he must be found so he can be �re-born�. John lets Mike take another solo flight, and Hsui Tai tries to contact �Kishnu� again; Mike manages to keep control and lands safely, and remembers the names �Hsui Tai� and �Kishnu�; he and John are convinced that Hsui Tai is a Tomorrow Person, and Tim finds some newspaper articles featuring the names, and claims that the Shansu sect kill the �Child Gods� when they reach maturity so that they can be re-born into a new body. John and Mike try unsuccessfully to make contact with Hsui Tai, who, meanwhile, is told by Matsu Tan that it is time for her re-birth. John and Mike attempt to reproduce the conditions when Hsui Tai first made contact by flying John's glider again, but the weather conditions are too dangerous. Mike sneaks back to the glider and tries a solo flight, just as the ceremony of Hsui Tai's re-birth begins; she makes contact with Mike and he loses control of the glider, crashing it.
Mike somehow appears in the temple, bound in front of the flames next to Hsui Tai. Finding just the crashed glider and Mike's jaunting band, John telepathically contacts his friend, and Mike tells him that he is in the temple, where the monks think he is Kishnu. Hsui Tai picks up the telepathy, and Mike tries to persuade her to leave the temple, but she refuses, instead going into a meditative trance. Tim tracks Mike's co-ordinates, and John remarks that he will jaunt there with a jaunting band and a matter transporter for Hsui Tai, but the Sage overhears the conversation between Mike and Hsui Tai, and confronts Mike, telling him to leave without Hsui Tai. John arrives and overpowers the Sage, and he and Mike take Hsui Tai back to the Lab. After a while Hsui Tai comes out of her trance, but refuses to believe that she is not a god. After some of the monks become afraid and want to leave the temple, the Sage decides to find Hsui Tai and Mike and complete the re-birth ceremony. John and Mike explain to Hsui Tai who the Tomorrow People are, and show her how to jaunt. The Sage tells Matsu Tan that they must start the re-birth ceremony for one of the �other� gods. Hsui Tai tells John and Mike about these other gods, and the two decide to rescue them; they all jaunt to the temple, where the re-birth ceremony has begun, but Hsui Tai refuses to interfere in it, and after a struggle, takes Mike�s stun gun. John and Mike find the re-birth chamber and are attacked, but Mike manages to stun everyone in the chamber, while John releases the child. Hsui Tai arrives and uses the stun gun to stun John and Mike. The two awake to find themselves chained up in the ceremony chamber, along with Hsui Tai, who asks why John has been chained up as he cannot be re-born. Matsu Tan tries to release John, but is stopped by the Sage, who begins the ceremony, Hsui Tai jaunts back to the Lab, and returns with two stun guns, which she uses to stun everyone and stop the ceremony. Hsui Tai decl
The driver of an army Major knocks down and kills a young boy who looks fourteen years old and wears a Nazi uniform. In the Lab, John shows Hsui Tai a baby rat that is over seven years old - they normally only live to three or four - and explains that he is repeating an experiment the Americans tried, which stopped the aging process before maturity, causing the normal repair processes to work more efficiently, and giving the subject longer life. Tim shows them film of Adolf Hitler inspecting the laboratory of Professor Friedl, who was carrying out the same experiments in the 1940's. Mike arrives wearing parts of an SS uniform, which John tells him in disgust to take off before going out. Meanwhile, in an SS bunker, leader Karl Brandt gives a speech to his cadets in order boost their morale following the escape of one of their number; the cadets have been in the bunker for thirty-three years, since the defeat of Germany at the end of the Second World War. The cadets look after the sleepers, people held in suspended animation. Mike goes to a cafe without his uniform, but three youths wearing SS uniforms and calling themselves �Storm Troopers� attack him for being in their meeting place. Mike returns with a black eye to the Lab, where John tells him that there were gangs of young people all over the world who have developed a fascination for Nazi uniforms. One of the SS cadets finds some fluid leaking from the suspended animation equipment, and the inside person is dead. Tim receives a call on the special telephone line from Major Hughes of the SIS Special Squad, and John sends him a matter transporter to bring him to the Lab. The Major tells them about the boy being killed: German records show that he was born in 1930, and should have been forty-seven, and he also appeared in the film of Hitler Tim showed earlier. In the bunker, Karl decides to wake up Professor Friedl to ask his advice. Mike returns in uniform to the caf�, where the �Storm Troopers� are bet
John believes that the Nazis used genetic engineering at the end of the war. Major Hughes and some British soldiers from a local military base search for the place that the SS cadet came from. When they find the hidden entrance, Professor Friedl suggests using a weapon called the �Sleeping Giant�. Tim tries an experiment on Mike: he shows him a picture of Hitler, which causes Mike to salute; then he shows Mike a picture of Neebor in his natural, disgusting state, which breaks the control. When Major Hughes finds the secret door, �Hitler� takes control of the British soldiers via a broadcast, and orders them to kill Major Hughes, but he escapes and goes to the Lab. The SS cadets plan to broadcast a television message to the youth of the world to make them follow Hitler's orders. John, Hsui Tai and Major Hughes jaunt to the bunker, while Mike stays behind. John uses a stun gun to incapacitate the British soldiers, but �Hitler�, Karl and Professor Friedl go to the television studio, but they can only broadcast to a few European countries. John, Hsui Tai and Major Hughes jaunt into the television studio and stun the Professor and �Hitler�, but Karl arrives and forces John and Hsui Tai to drop their stun guns. When �Hitler� was stunned he lost control of his shape-changing, and he reverts to his natural state. Mike jaunts into the room and stuns everyone, including his friends, and tells �Hitler� to continue with the broadcast. As �Hitler� begins, he is stunned by Mike, causing him to revert once more, and this breaks the control of everyone watching.
When a small spaceship crashes into the Pacific Ocean region on Earth it causes an Earthquake, which is felt in the Tomorrow People�s Lab. The spaceship is piloted by two Thargons, Flyn and Sula, who have escaped from the fleet�s main �Thick Ship� in a short-range �Slim Ship�, which they have deliberately crashed into the Earth in order to bury it, and so escape detection from space. Believing the crash to have been caused by a meteorite, Tim traces the impact point to the island of Tarpin, part of the Melosean chain of islands. Mike and Hsui Tai jaunt to the island, but when Flyn and Sula decide to raise the ship to the surface, Hsui Tai is blinded by the engines. Back at the Lab, John repairs Hsui Tai�s eyes. A military airplane spots the �Slim Ship�, and its pilot reports back to the dictator General Papa Minn, who orders Major Marcos to investigate with troops. John, Mike and Hsui Tai return to the island and meet Flyn, Sula and Thing, the ship�s computer, and are told by the aliens that they are on the run from the ruthless Thargon Overlords for opposing the massacre of their slaves. Flyn warns the Tomorrow People that the Thargon Overlords will destroy the Earth when they find Flyn and Sula there.
Flyn and Sula offer to build a Ripper Ray to defend the Earth, but the Tomorrow People decline. John and Hsui Tai return to the Lab while Mike stays with Flyn and Sula. But Major Marcos arrives and knocks Mike unconscious. Meanwhile, the Galactic Federation have found the two thick ships. Flyn and Sula accompany the Major to see General Papa Minn. John jaunts to the Thargon thick ship to confront the Captain, who tells him that there are no slaves and no Overlords on their planet, and that Flyn and Sula are criminals. Flyn and Sula offer to show General Papa Minn how to build a Ripper Ray and use it to rule the Earth. After Mike regains consciousness he is told by Thing that the Thargon Overlords have re-captured Flyn and Sula, and so he returns to the Lab. Flyn, Sula and the General return to the slim ship, and the two aliens begin building the Ripper Ray. The Tomorrow People return to the slim ship but are seen by soldiers. John and Mike jaunt back to the Lab, but Hsui Tai is shot. Flyn, Sula and the General prepare to launch the slim ship so that the General can deliver his ultimatum, but John and Mike rescue Hsui Tai just before the slim ship lifts off, its blast destroying the island. The General forces Flyn and Sula to allow him to broadcast his demands, and to fire the Ripper Ray. The blast is detected by the Thargon thick ship, which heads for Earth.
At a hotel near Loch Ness, the barman, Angus MacDuff sees a ghost. At the same time, the Tomorrow People see the ghost in their dreams, and think it may be another Homo Superior attempting to communicate. At the Forbes hotel, the proprietor�s son Andrew suggests to his father, Bruce that they advertise the place as haunted, and he shows him that he can create a ghost. But Bruce thinks that the ghosts are the Devil�s work, and warns Andrew not to make them again. Andrew talks to some American researchers, lead by Dr. Gail Mayer, who are staying at the hotel while they look for the Loch Ness Monster. Andrew creates an illusion of the Monster in the Loch in front of the researchers; the image is also seen by John, Elizabeth, Mike and Hsui Tai. The researchers are very excited and contact the media. The Tomorrow People see the reports, and theorise that a member of the Loch Ness research team may be breaking out and telepathically transmitting images. John, Elizabeth, Mike and Hsui Tai jaunt to the hotel. Bruce is furious when he finds out about his son�s creation of the monster, and locks the boy in the cellar.
The Tomorrow People talk to Doctor Mayer about the monster, but she denies that anyone has seen a ghost; but when Angus tells them about seeing his ghost, Doctor Mayer notes that Andrew was with them when they saw the monster. After Gail tries unsuccessfully to find Andrew, Angus goes to the cellar and finds the boy locked up. Andrew creates an illusion that frightens Angus into unlocking the door, but Bruce tries to stop Angus and they are both injured in the confusion. They are found by John and Elizabeth, who take them back to the Lab, leaving Hsui Tai and Mike to check the rest of the hotel. Andrew creates more illusions to escape from Mike, who is knocked unconscious. Andrew leaves the hotel on a bicycle. Angus thinks that his son may hide in a tower near the hotel, and as the Tomorrow People and Bruce arrive there, Andrew creates an illusion of a band of Scots warriors. The Tomorrow People create a group of Redcoats to counter the attack. After the battle Mike jaunts to the top of the tower and persuades Andrew to join them, and Bruce allows Andrew to create ghosts at the hotel to attract visitors.
A pair of odd aliens arrive on Earth with the purpose of mining a rare mineral, which can suppress telepathic powers.
To save the Earth, the Tomorrow People must overcome two criminal aliens but without the use of their telepathic abilities.
The Ballboids have come to Earth, and are disguising themselves as trendy jumpsuits. The harmless fashion is really their way of easily taking over the minds and bodies of the Earth's population.
The Tomorrow People use a cold virus to battle the parasitic Ballboids.
Elizabeth and Timus are negotiating with a representative of the Sorsons - a race of advanced non-humanoid aliens - to try to end the war between them and the Thargons, but their attempts are unsuccessful. Elizabeth contacts the Lab and tells her fellow Tomorrow People that the Galactic Federation is powerless to prevent the Sorsons and Thargons entering Earth's area of closed space. After the Sorsons land on the moon and begin construction of a base, the President of the United States of America sends a space-shuttle to investigate. Tim detects the arrival of the Sorson and Thargon spaceships, and John and Mike decide to jaunt up to try to stop any fighting; but the battle begins before they can act, and the American space-shuttle is caught in the middle. John and Mike save the crewmen, Evans and Ricardo, by using matter transporters to send them back to their base; however, despite contacting both fleets, they are unable to prevent the battle from ending.
Elizabeth returns to the Lab, just as General Vishishnu and his Sorson fleet enter Earth�s atmosphere; one ship lands near the White House and the Sorson representative promises to help the President defend the planet, and gives him a Barluminite raygun to stop the Tomorrow People interfering without harming them. John and Elizabeth jaunt to the Galactic Trig to discuss the Sorson landing on Earth, but the committee�s lack of interest angers John, and he is charged with contempt by the chairman, arrested, and sent to the Proctor Detention Centre with his telepathic powers removed. Mike and Hsui Tai jaunt to the White House, but the President accuses them working for an alien power and withholding advanced technology, and shoots Mike.
The President imprisons Mike and Hsui Tai. The Sorson General, Vishishnu, begins training American pilots, including Evans, so that they can defend the solar system. Andrew jaunts to the Oval Office to rescue his friends, but is captured after the President uses the Barluminite raygun on him. But Andrew is only pretending: he ducked when the gun was fired, and he uses matter transporting bands to return to the Lab with Mike and Hsui Tai. Andrew suggests threatening the Trig with a Sorson spaceship in order to rescue John, and they jaunt onto one of the spaceships. Eliciting the aid of Evans, they travel to the Trig, where an artificial intelligence refuses to release John until his case has been heard. Evans opens fire, and the Chaircreature releases him. The Tomorrow People return to the Lab, where Tim, defying instructions from the Federation, informs them that their membership has been suspended. Meanwhile, the Sorson General is furious that Evans has taken a ship and destroyed other Sorson ships, and tells the President that his fleet will depart, leaving the planet at the mercy of a Thargon fleet heading for Earth.
Earth faces danger from two directions: the Thargons and the Sorsons. The Tomorrow People must somehow defeat them both to save the planet.
