Andre Morell stars as Professor Bernard Quatermass in this landmark television classic. When a strange capsule is unearthed at an archaeological excavation in London, an unexploded bomb is initially suspected. However, with a history of supernatural events in the area going back many centuries and with events at the dig site about to take an unexpectedly alien turn, the origins of the capsule are soon revealed to be far more distant than anyone could have imagined. When the capsule is finally opened, something is unleashed upon the streets of London that nobody can control and mankind's past and future collide with devastating consequences.
The serial sees Professor Bernard Quatermass of the British Experimental Rocket Group being asked to examine strange meteorite showers. His investigations lead to his uncovering a conspiracy involving alien infiltration at the highest levels of the British Government. As even some of Quatermass's closest colleagues fall victim to the alien influence, he is forced to use his own unsafe rocket prototype, which recently caused a nuclear disaster at an Australian testing range, to prevent the aliens from taking over mankind.
Set in the near future against the background of a British space programme, it tells the story of the first manned flight into space, overseen by Professor Bernard Quatermass of the British Experimental Rocket Group. When the spaceship that carried the first successful crew returns to Earth, two of the three astronauts are missing, and the third is behaving strangely. It becomes clear that an alien presence entered the ship during its flight, and Quatermass and his associates must prevent the alien from destroying the world.
