The Trial of a Time Lord Synopsis
The TARDIS is drawn to a space station where the Doctor 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 his 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, which turns out to be a future Earth, shifted light-years through space.
