Doctor Who: The Mysterious Planet(Doctor Who: The Trial of a Time Lord, Parts One to Four)

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 space-time excursions, which have threatened the sanctity of the universe. Indignant at these accusations, the Doctor pleads his case to the Inquisitor with the hope that she will see him as a source of hope and goodwill for existence. However, his prosecuting attorney, a sinister Time Lord known simply as the Valeyard, begins a crusade against the Doctor's life with the motive of painting him out to be a villainous renegade.
