The Doctor is pulled out of his time stream and summoned to a Time Lord space station above Gallifrey. On his arrival it is announced by the Inquisitor that the Doctor will stand trial. Accused of conduct unbecoming a Time Lord, the Doctor refutes the allegations made against him and chooses to mount his own defense rather than entrust his fate to a fellow Time Lord. Opposing the Doctor and appearing for the prosecution is the Valeyard, an enigmatic figure who is clearly out for the Doctor. Suffering from short term memory loss as a result being taken out of time, and puzzled as to the absence of his companion Peri, the Doctor can only sit back and watch as the Valeyard mounts his case against the eccentric time traveler. The first piece of evidence is taken from the Matrix, the repository of all Time Lord knowledge. It chronicles the Doctor's interference in affairs of the planet Ravalox, a planet very similar to Earth and which was partly decimated by a fireball several centuries ... Written by
Did You Know?
Head of Drama Jonathan Powell took issue with several aspects of The Mysterious Planet, most notably its humourous content, the level of the Doctor's involvement in the events on Ravolox, and the gradual introduction of the Trial scenario. Robert Holmes
-- who by now was ill with liver-related difficulties - was frustrated by Powell's last-minute indictment of his story, as it meant he would have to suspend work on the season finale to return to a set of scripts he believed were long since finished. Eric Saward
, for his part, was livid, believing that Powell was demonstrating a lack of respect for the veteran writer. Things were not helped by the fact that Saward's relationship with John Nathan-Turner
was deteriorating, with the script editor feeling his producer was expending too much time wooing the show's American fan base. See more

I may look old to you, wiskerless youth, but I'll have you know I'm in the prime of my life. I'm only nine-hundred years old.
