Doctor Who (1963) - New Beginnings (Keeper Of Traken / Logopolis / Castrovalva) (3 Disc Box Set)

Contains three classic Doctor Who stories from 1981-82:

"The Keeper of Traken":
Returning to N-Space, The Doctor and Adric are summoned to Traken, a planet of peace and harmony, where The Keeper of Traken is nearing the end of his 1000 year old keeper-ship and one of the Counsels of Traken is to become the next Keeper. Where The Doctor, Adric, Tremas, one of the Counsels elected to become Keeper and Tremas's daughter Nyssa set out to stop the evil Melkur, believed to be a "Source of Evil" that is trying to destroy the Union. Only to discover Melkur is being used by a old enemy of the Doctor, The Master, who plans to take control of The Source, The Union's keystone, so he can regenerate into a new body.

"Logopolis":
The Doctor takes Adric and a young air hostess named Tegan Jovanka, who has come aboard the TARDIS by accident, to the planet Logopolis, home of a race of mathematicians whose help he hopes to enlist in reconfiguring the outer shell of the TARDIS. The mysterious, wraith-like Watcher brings Nyssa from Traken to join them and warns of impending danger - something that is borne out as the Master arrives and kills a number of the Logopolitans.

"Castrovalva":
The newly regenerated Doctor escapes with his companions back to the TARDIS. Suffering from post-regeneration trauma, he only narrowly manages to save the ship from destruction as it plunges back to Event One, the hydrogen in-rush that preceded the creation of the universe. He then seeks sanctuary in the peaceful domain of Castrovalva, only to discover that it is an illusory, dimensionally paradoxical trap set for him by the Master with the unwilling aid of a kidnapped Adric.
