Recap: Doctor Who S6 E2 "The Mind Robber"
Not all unicorns are of the friendly, cutesy sort.
We obey our creator, that is all that can be expected of any character, unless the Master bids us otherwise.
— Lemuel Gulliver
To escape from the lava flow at the end of The Dominators
, the Doctor hits the emergency switch, zapping the TARDIS out of space-time and into a featureless white void, where they are attacked by white robots (some "void").
And then things get weird
They flee back to the TARDIS which promptly explodes, leaving Jamie and Zoe clinging to the control console in space, while the Doctor appears to be dead. Suddenly, they find themselves in what appears to be a fictional landscape, menaced by lifesize clockworks soldiers and meeting characters like Gulliver and Rapunzel.
The Doctor discovers that they are in the Land of Fiction, a realm of a different dimension presided over by The Master of the Land (not that
Master, thankfully): an English writer from the 1920s who has been yanked out of his own time and is being controlled by the Master Brain computer. The Master wants the Doctor to take his place and the two enter a battle of wills using fictional characters.
Zoe and Jamie arrive and succeed in overloading the Master Brain, which is then destroyed in the confusion by the White Robots, freeing the Master and allowing the Doctor and friends to escape.
This is the only serial to use episodes of 20 minutes rather than the usual 25. Watch it here.
