An emergency forces the travel machine out of the time space dimension and it lands outside of reality. The Doctor and his crew enter a fantasy world of white robots and fictional monsters that come to life. They soon discover it is also a realm of great danger, for it is the home of the Unicorn, Minotaur and Medusa.

Adventures and travels of a Time Lord known as The Doctor, who employs a time-and-space travel device in the shape of a typical British Police Box (Booth).
In "The Mind Robber" The Doctor explores a fantastic world of robots.

Distributor Notes: A quick escape from the path of molten lava sends the Tardis to "nowhere" where anything that springs to mind may become reality.
