Doctor Who: Shada (UK-import)
Never aired on television due to a strike, and never fully completed, this 6 part adventure traces the chase to recover a powerful book, the Artifacts of Gallifrey, stolen from a retired timelord, Professor Chronotis. Skagra is the evil despot responsible for this foul jiggery pokery. Original footage from the show was used as the Fourth Doctor's involvement in 'The Five Doctors', before it was reassembled for this video release, with an older and portlier Tom Baker narrating the missing gaps.
