This four-disc BBC box-set features the episodes of the classic science fiction series - The Mysterious Planet, Mind Warp, Terror Of The Vervoids and The Ultimate Foe - that make up the Trial of a Time Lord storyline. The TARDIS is drawn to a space station where the Doctor (Colin Baker) is subjected to a Time Lord inquiry into his behaviour, presided over by an Inquisitor. The prosecuting counsel, the Valeyard, presents the first piece of evidence, which consists of a recording played back on a screen linked to the Matrix. It concerns a visit by the Doctor and Peri to the desolate planet Ravolox.
