Doctor Who: Shada
First on BBC One, a little later than originally billed...
Overview
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.
