The Doctor visits his old Time Lord friend Chronotis in Cambridge, 1979. But the ruthless Skagra has also arrived to retrieve a book that will help unlock one of the Time Lords' greatest secrets: what is Shada? Filming for this story was never finished, and in this version the unfilmed material is completed via animation.
The story revolves around the lost planet Shada, on which the Time Lords built a prison for defeated would-be conquerors of the universe. Skagra, one such inmate, needs the help of one of the prison's inmates. He finds nobody knows where Shada is anymore except one aged Time Lord who has retired to Earth, where he is a professor at St. Cedd's College, Cambridge. Luckily for the universe, Skagra's attempt to force the information out of Professor Chronotis coincides with a visit by the professor's old friend, the Doctor. (Filming for this story was never finished, and in this version the story is completed via on-camera narration.)
Adaptation of the Barbara Vine (aka Ruth Rendell) novel. After Adam inherits a country house from his great uncle, he and his friend Rufus decide to spend the summer there instead of abroad. An odd assortment of 'house guests' turns up through different means and it's an uneasy mix at best. A decade afterwards, the bodies of a young woman and an infant are discovered in the woods behind the house. As the police investigate, they naturally look to Adam as former owner of the house, and what happened all those years before starts to catch up with him.
