Dr. Who arrives at the village, and comes across many people behaving strangely. Sometimes they ignore him, sometimes they repeat their actions and words, and sometimes they refer to sheets of paper they are carrying.
He finds a young boy, Timmy Drake, whose father is a local celebrity and is acting strangely along with the others. Timmy tells Dr. Who that TV scientist Jeremiah Scratch is in charge of the dig. Timmy saw him carrying a strange glass globe containing a kind of moss inside.
Dr. Who confronts Scratch, who wants to destroy the evil force of television and is working for aliens, specifically a Klepton parasite. Dr. Who convinces Scratch that the moss lied to him, and he helps Dr Who free the villagers from hypnotism. Dr. Who neutralises the polarity of the Klepton's machine, and it is reduced to dust.
