The Doctor, The Valeyard and The Inquisitor sit down to MST3K a great episode of Doctor Who
Doc is on trial! It would seem that the Time Lords have been monitoring his exploits and aren’t too happy with the way he’s interfered with other life forms and civilizations. The prosecution, trying to hold Doc to account, is in the form of a Gallifreyan called the Valeyard (or Scrapyard as Doc would much rather call him). And the judge is called The Inquisitor, so it’s quite clear that the Time Lords are as mad as a box of frogs and the concept of a “fair trial” might be missing from these proceedings. The first piece of evidence the Valeyard would like the court, mainly The Inquisitor herself, to consider is a convenient 20-ish minute playback of this one time that Doc and Peri went to Ravolox, a suspiciously Earth-like planet that was meant to have been fireballed to death and yet seems a very green and pleasant land.
Oh ho, plot twist. Ravolox is in fact Earth, it’s just a couple of light years away from where it’s meant to be. That’s not as big a plot point as it might seem though; the real problem is that there’s a crazy robot running around the place calling himself The Immortal and trying to oppress the few hundred remaining organics (a.k.a. humans). The Immortal, or Drathro to his friends, is powered by a black light machine. Unfortunately, said machine is compromised by the mercenary duo of Glitz and Dibber. Without Doc’s intervention, there’s a real possibility that this black light machine could kill all life on the planet or even, the whole universe. Objection! Sustained. Said intervention might not wholly conform to Gallifreyan law. Dum dum dum!
