The Third Doctor (Jon Pertwee) is back in the show's ninth season. In "Day of the Daleks," a 22nd-century battle between the merciless metal monsters and human freedom fighters stretches across time to 20th-century Earth. Can the Doctor and Jo Grant (Katy Manning) help save mankind's present and future, or will both be "exterminated"? Dispatched by the Time Lords to oversee the entry of the planet Peladon to the Galactic Federation, the Doctor and Jo attempt to learn who is willing to resort to murder to stop the joining, before interplanetary war erupts, in "The Curse of Peladon." It's twice the menace for the Doctor when his old foe, the Master (Roger Delgado), teams up with "The Sea Devils" in a plan for world domination. Then, on a clandestine mission to the planet Solos in the distant future, the Doctor and Jo aid the native Solosians from both an imperial Earth marshal's evil schemes and a devastating disease, in "The Mutants." And, the Doctor and Jo must prevent the Master from unleashing "The Time Monster"-an extratemporal creature called Kronos-during a trip back to a pre-sinking Atlantis.26 episodes on 8 discs.
