It's been six months since Ryan and his friends got trapped on The Island. They build a raft but get caught in a storm. The raft breaks, causing the kids to end up on a new island, separated from each other. Josh and Ryan soon find each other trapped in a hole; Jarrah and Gabe also find each other, and they later find Zuke. Lily and Em are also together, but Natasha and the mystery girl (from the last episode of Trapped) are nowhere to be found. Ryan and Josh are helped out of the hole by a girl named Saskia, who is also trapped on the island. But is she to be trusted?
It's morning, Lily and Em goes out to find the others but when they take a shortcut over a field most covered in mud, Lily gets mud in her eye and tells Em to quick go and get water but instead of water, she finds three strangers in masks who starts to chase her. Meanwhile Josh starts to becomes friends with Saskia but Ryan is still not sure if he should trust her since she tried to steal the antidote.
Gabe went away to get some fruit but instead, he found the strangers in masks but he doesn't tell Jarrah and Zuke but later the strangers kidnap Zuke. Lily and Em are finally together with Ryan and Josh but Saskia is also there and she seems to know the strangers in masks.
The strangers in masks has captured Ryan and his friends (Natasha and mystery girl not included) with some assistance from Saskia and they have been captured in a cage in a camp full of kids and no adults. Saskia has stolen the antidote so later when Ryan has escaped he gets a disguise and come back to the camp to save his friends and get back the antidote.
Ryan has the antidote again and he has also decided that they are going to stay at the camp for a while. Later they participate in a ritual and during the ritual, Ryan and his friends find out that the other kids in the camp also are kids to scientists who Dr Hamilton has imprisoned.
Ryan and his friends are preparing to leave but there not the only people preparing since all the other kids also wants to join them since they think the antidote is magical and can protect them. The leader Dionne is against the other kids leaving and she shows Ryan that some other kids that tried to leave the camp where found dead. Meanwhile, Em and her friend Max (Jacob Clarke) play pranks and get in trouble.
To protect the kids, Ryan has thrown away the antidote but later he goes to search for it, he finds the enterprise package but he pretends that he found it. It's a new day and Lily, Josh, Gabe, Dionne and some other kids are on a journey for honey but they also find a carriage that belonged to a woman named Cath and her daughter but there's no sign of them.
They don't find Cath and her daughter but they found out something else, Cath's last name is Schwartz and she's Gabe's mother. A few days later, back in camp, Ryan finds out that Dionne has the antidote and Dionne says that if he tells anyone about it, she will pour it out. Meanwhile Saskia is trying to become friends with Josh again but Josh is still seems to hate her so Em and Gemma (Logan Deiley) tries to solve it by putting them in the cage.
Ryan and Jarrah have been kicked out of the camp without the antidote but Saskia steals it, gives it to Josh and he gives it to Ryan. When Ryan got the antidote, they start their trip to find Dr. Hamilton but they notice that they are followed but Ryan finds out that it's Gabe. Gabe is there because he wants the antidote and after some discussion, Ryan gives it to him. Meanwhile, Jarrah is out looking for water but instead she finds Natasha and the Mystery Girl who's called Hope (Luisa Mitchell). Natasha has injured her ankle so Jarrah says she will go and get Ryan but is she really going to tell Ryan.
Natasha and Hope are lucky because while Jarrah didn't tell Ryan and Gabe about Natasha and Hope, Gabe found them and helped them to get to the camp. Jarrah and Ryan continue their journey but need to return to camp since Jarrah has been bitten by a snake. Back at camp they help Natasha with her ankle and to cheer her up, they invent and perform a play about how much Ryan misses her.
There is some trouble back in camp, Ryan has love trouble with Natasha and Jarrah and there are some kidnappers tying to kidnap the kids and the kidnappers seems to have some assistance from Saskia. Besides this there are some extra love trouble, Sasika and Josh are a couple but Lily has started to like Josh too. In the end, two of these troubles are over, the kidnappers kidnapped Tom (Louis Biggs) and Natasha breaks up with Ryan.
Lily and Jarrah are getting really suspicious and they know there's something wrong about Saskia. They go to through her stuff and finds a codebook but when Saskia finds out she throws it in the fire and then Lily and Jarrah really knows there is something wrong. Later they find a note written in Morse code and with help from Zuke, they have real evidence that she works with the kidnappers.
It's almost time to leave the camp but a house falls down and since Zuke accidentally made the house fall, they stay to re-build the house. Zuke tells Em about how he made the house fall and that he doesn't want to leave the camp since he also knows about the kids who died. Later their carriage also breaks and it is Zuke this time also. Jarrah decides that she and Zuke will stay. Meanwhile, Natasha tries to get the kids to stop being afraid for Dr. Hamilton but it ends up with Natasha telling them that she is his daughter.
Ryan, Natasha, Gabe, Josh and Lily has left Jarrah, Zuke, Em and the other kids at the camp and begins their journey to the Enterprise base where they hope to find their families. At the beginning of the journey, it turns out that Em has followed them since they left the camp and after some arguing with Lily, she gets to stay. Natasha and Ryan are still fighting but to solve it, Lily and Josh sends them to find water. Instead of water, Natasha, Gabe and Ryan finds an old Enterprise base that also was the base where the kids back in camp came from.
It has been a week since Ryan, Natasha, Gabe, Josh, Lily, and Em left camp, and they are out of food and water. After freeing the cart from a sand dune, Gabe falls over a rope that leads to a raft. Gabe and Em take the cart to search for water while the others fix the raft and prepare it for fishing. In a ploy to get Ryan and Natasha back together, Josh and Lily offer to take the raft out fishing, leaving the former lovers to search for Saskia’s trail. While searching for the trail, Ryan and Natasha hear the motor of a boat. They try to wave it down but are unsuccessful. As Ryan and Natasha finally talk about their relationship, Lily tries to cope with her unrequited feelings for Josh. The group reunites over a dinner of fish and fresh water, but someone from Enterprise is watching them as well.
Ryan and his friends are getting closer to the Enterprise base, but they remain unaware that a Snatcher is watching them. After being tricked into thinking that there are dingoes nearby, the group decides to leave the trail in order to find a safer way around the animals. While Ryan and Natasha go ahead to find an alternate route, the others stay back to rest up before their journey. Fed up with the others’ decision to rest up before leaving the trail, Em steals the antidote and runs away. Gabe finds her and convinces her to return to the others. Just as they reunite, they see the Snatcher that was spying on them and chase him. Meanwhile, Ryan and Natasha find a path and an old caravan, which turns out to be where Dr. Hamilton started his research. A Snatcher overhears Natasha say that she is Dr. Hamilton’s daughter and kidnaps her after she has an argument with Ryan. The others look for her but only find the remains of a trap and Natasha’s blood on the ground.
With Natasha gone, everyone is on high alert. Gabe notices someone spying on them and works with Ryan to capture the spy, who turns out to be a kid. The kid reveals that Dr. Hamilton isn’t at the Enterprise Base and that someone else is in charge. Gabe and the others release the kid against Ryan’s wishes, knowing that the kid will inadvertently lead them straight to the camp. Back at the camp, Saskia is helping tend to Natasha, who remains unconscious. The spy, Ned, returns to camp but does not tell Saskia that he had been caught. After breaking a wheel off the cart, Ryan and Gabe go ahead to check out the camp while the others fix the wheel and follow behind. Josh and Lily finally share their first kiss, but it doesn’t turn out as well as they thought as Lily tells Em it was like kissing a brother. Ryan and Gabe arrive at the camp and discover that there are no adults there at all. Em, Lily, Gabe, and Josh are reunited with Saskia while Ryan is taken to see Natasha. Natasha introduces Ryan to her old friend and the leader of the camp, Eli Fox.
While Ryan and his friends remain suspicious of the base, Natasha tries to convince them that everything is alright: it was the pharmaceutical companies that caused the trouble; her father is finishing his research, legally this time; and the kids at the base are working there to gain experience. Ryan goes snooping to find evidence that would prove that what the kids are doing is unsafe and accidentally destroys two weeks of research in the process. Even after promising Natasha that he’ll keep an open mind, Ryan goes snooping again, this time finding a map that shows the camp as well as a nearby "Forbidden Area." Ryan heads to the Forbidden Area but runs into some falling rocks and needs Eli to save him. Still, Ryan tells Gabe that he still doesn’t believe Eli as Eli eavesdrops on their conversation. Meanwhile, Lily finds out that she doesn't like Josh anymore but she doesn't break up with him since she doesn't want him to get back with Saskia. Unfortunately, Josh hears Lily talking to Em about all of this.
While helping a girl named Bonnie (Baillie Millar) with some algae, Josh decides to play a joke on her by pushing her into the water. Unfortunately, she gets stung by a jellyfish, and Josh gets Ryan and Eli to help her. Eli overhears Josh ask Ryan about using the antidote and later questions Saksia about it. Having overheard Ryan say that they left it in the cart, Eli tricks Natasha into bringing the cart (which had been abandoned a short distance from the camp) back to camp. While Eli, Natasha, Lily, and Ryan head out to find the cart, Josh and Em unsuccessfully try to cheer up Bonnie. When Ryan and Eli find the cart, Ryan tells Eli that the antidote is gone, but he has actually just hidden it. Eli, Saksia and Bonnie then pretend that Bonnie has gone into shock and cure her with an antidote of their own. Ryan falls for the act and believes they no longer need the antidote. With Ryan's guard down, Eli steals the antidote.
Although Ryan and his friends have been tricked into believing Eli, Lily and Gabe still feel that something is wrong about the entire situation. Gabe’s suspicions are only heightened when he finds Bonnie stealing something from the kids’ tent. Bonnie hides the stolen object in a locker, so Gabe enlists Lily and Em to help him break into the locker. Not only do the kids discover that Bonnie took a walkie-talkie, they learn that her real name is Ebony and that she’s Gabe’s sister. When Gabe confronts Ebony about this new information, she accuses him of trying to trick her. She later believes him but runs off before she can tell him about their mother. Meanwhile, Natasha convinces Ryan to help Eli for the day. After Eli treats Ryan for an algae sting, Ryan begins to trust the leader. His faith in Eli doesn’t last long, however, as Gabe, Lily, and Em have learned that the kids at the base are being forced to work with the threat of never seeing their parents again if they refuse.
To ensure that they will see their parents again, Ryan devises a plan to steal some algae and use it to make a deal with Eli. The plan goes awry, however, when Tom tells the gang that the algae will rot if it is not kept in a cold environment. Meanwhile, Eli woos Natasha while she is upset with Ryan. When Natasha finds the antidote on Eli’s desk, he confesses that Bonnie faked being sick. Taking the antidote with her, Natasha leaves Eli, telling him that Ryan and Saskia were right about him all along. Saskia intercepts Natasha and reveals that Eli has a crush on her, driving Natasha back to Eli.
Pressured to reach the quota by the end of the week, Eli launches an expedition to find more kids to bring to the base. While the snatchers search for kids in the community, Jarrah attempts to steal their boat. The snatchers come back with Zuke before she is able to get away, so Jarrah allows herself to be captured in order to save her brother. On the boat, Jarrah manages to stop the engine so Zuke can escape. Jarrah is taken to the base. Meanwhile, drama continues with Natasha, Eli and Ryan. Saskia, upset with Eli’s expedition, tricks Eli into telling her about that he didn't really like Natasha while Natasha is listening. After realizing that Eli was just using her, Natasha apologizes to Ryan. When Ryan finds out that Natasha approved the snatchers going back to the community, however, he breaks up with Natasha.
The work at the base is done and the boats are coming to pick up all the kids, or at least that's what the kids think. There is only 1 boat that will come and it's reserved for Eli and Natasha, the rest of the kids will be left at the base for the rest of their life. Saskia finds out about it that they will be left there (but not about that there will be only one boat) and She decides that Josh and her self are going back to the camp to convince Dionne, Zuke and the other kids to leave the camp and help them with hijack the boats.
Josh and Saskia has arrived to the camp and after showing the kids some files about their families, they manage to convince them to join them back at the base. They start to transport some of the kids to the base but then, when the engine breaks, the rest of the kids, Josh and Saskia included, have to walk all the way back to the base. Meanwhile at the base, Ryan has found out about the boat plan and he ruins all the algae in anger. Bonnie finds out that there will be only one boat and that it will stop at another beach they've been told so Eli lock her up.
The only boat has left and the only passengers are Eli and Natasha; they get to the enterprise base but get thrown out because they don't have any algae and because Dr. Hamilton doesn't want to be disturbed by his family during his work. Meanwhile, the boat back at the base is fixed so while the rest of the kids start to walk to the city, Josh and Ryan starts to go by boat to the city where Dr. Hamilton but the boat breaks and then they get rescued by a fisherman but for real, he's working for Dr. Hamilton. They get chased through the city and in the end they get caught and locked up but Eli and another guy called Marcus (Nick Britton) but they was searching for the antidote which they didn't have because Natasha has given it to Gabe.
All the kids have arrived at Dr. Hamilton's base and they hide in a big storage room while Lily, Em, Josh and Saskia goes searching for their parents and Ryan and Gabe goes searching for Dr. Hamilton. Lily and Em finds Gabe's mom, and Eli finds Gabe and Ryan but he says that Natasha is the one who wants the antidote because he has tried one of his antidotes on himself and he's dying. They manage to get to him in time but Eli wants a drop of the antidote but when Natasha says no, he steals it and runs away. Lily finds everyone's parents locked up in another storage room and with Saskia and Josh they release everyone and reunite. Meanwhile Natasha and Ryan get on a boat and chase Eli and drive him back to shore where Ryan tackles him to the ground and almost all the antidote spills out. There is only one drop left and Natasha uses it to save her dying father. Dr. Hamilton wakes up and apologizes to his daughter. Ryan and Natasha then hug and kiss and the episode ends.
