In a priory near the village of Fetchborough, four scientists, Adam Colby, Max Stael, Thea Ransome and Dr. Fendelman, are doing tests on a human skull they found in Kenya, apparently twelve million years old. When Dr. Fendelman starts using a sonic time scan, trying to get an image of the owner of the skull, the skull itself seems to react, locking onto Thea and releasing something in the priory grounds that kills a passing hiker, who eventually totally disintegrates. The scan catches the attention of the Fourth Doctor and Leela when they are pulled down to Earth by it. They set off to find it before it creates a continuum implosion and destroys the planet. They separate and Leela finds the cottage of ‘Mother’ Tyler, a local modern-day witch gifted with psychic powers. The Doctor ends up narrowly avoiding death at the hands of the creature created by the skull, which then kills the leader of a detachment of guards Fendelman has brought in after the death of the hiker, sealing everyone into the priory.
