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.

Blue Peter presenter Yvette Fielding takes Peter Davison, Mark Strickson and Janet Fielding on a trip through BBC Television Centre, meeting up with old friends and colleagues as they reminisce on their time spent working in the iconic building. With film traffic supervisor Neville Withers, assistant floor manager Sue Hedden, costume designer Odile Dicks-Mireaux, production assistant Jane Ashford, make-up artists Joan Stribling and Carolyn Perry, former BBC producer and writer Richard Marson, senior camera supervisor Alec Wheal, exhibitions assistant Bob Richardson and videotape engineer Simon Anthony.

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.)

The Doctor is summoned before the High Council of Time Lords to stand trial for the charges of harmful interference to the course of events during his travels which have threatened the sanctity of the universe.
