S01E01 The Sound of Silence
The Doctor arrives in the village of Linnet, Lancashire to find it eerily silent. He soon discovers that the locals, with the exception of the barmaid Alison Cheney, are terrified of strange creatures that live...
Alison has been implanted with a Shalka, which allows her to take control of the evacuees. The Doctor discovers that the aliens have mobilised other communities around the world in order to destroy Earth's atmosphere and wipe out humanity.
The Doctor, a time-traveling alien explorer, is sent by his people, the Time Lords, to liberate a small town in England from the tyrannical rule of a race of alien lava creatures called the Shalka.
