This Doctor Who episode aired in 1975.
On board a space station orbiting Earth, something opens up a compartment containing a sleeping human and enters it. Years later, the TARDIS materialises in a darkened room on board the station, and the Fourth Doctor, Sarah Jane Smith and Harry Sullivan emerge.
The Doctor notes that the alien insect has been dead for a long time and is almost mummified. Just then, one of the pallets activates and a woman revives from suspended animation. She introduces herself as Vira, a senior medical officer, and demands to know who the Doctor and Harry are.
The High Minister’s voice echoes through the Ark, identifying it as Space Station Nerva, praising the passengers for their efforts and encouraging them to rebuild human civilisation. Noah manages to fight off some of the alien influence and orders Vira via the communications system to expedite the revivification and get everyone off the station before the insect aliens (called the Wirrn), absorb them and take over the Earth. The Doctor and Vira go to find Noah while Harry and Sarah revive the rest of the technical crew.
Fortunately, Vira and Sarah have followed the Doctor. Vira shoots at Noah, allowing the Doctor to reach them. As they back out of the room, Noah tells Vira to leave the station in the transport ship, or else the Wirrn will hunt them down when they emerge. Noah explains that a thousand years ago, the Wirrn were driven from their home, Andromeda, by human space settlers. Since then, they have drifted through space, looking for a new world, and have now claimed the Ark for their own. While the Wirrn can live in space, their breeding colonies are terrestrial, and they need humans as hosts. They intend to absorb all human knowledge, achieving revenge for the loss of their original home and becoming an advanced technological species within a single generation.
