The Time Warrior:
Journalist Sarah Jane Smith is impersonating her aunt, virologist Lavinia Smith, in order to gain access to a research centre where top scientists are being held in protective custody while UNIT investigates the disappearance of a number of their colleagues. The missing scientists have been kidnapped by a Sontaran, Linx, and taken back to medieval England, where they are working under hypnosis to repair his crashed spaceship.

The Invasion of Time: (2 Disc Set)
Welcome to one of the most popular Doctor Who stories from the classic Tom Baker era.
The Doctor is behaving very oddly. After signing a treaty with enemy aliens, he returns to his home planet, Gallifrey, and demands the Presidency of the High Council of Time Lords. His first act of rule is to banish Leela to the wastelands on pain of death. His second is to sabotage the planet's defence barriers, enabling full scale invasion. Why has the Doctor joined forces with the militaristic Vardans? Is he out for revenge against the Time Lords? Or does he have a hidden agenda? But his allies are also hiding a dark secret, for behind them is a familiar enemy waiting for the right moment to attack...

The Two Doctors: (2 Disc Set)
The Doctor comes face to face with himself in 20th Century Seville, where he discovers that his old adversaries, the Sontarans, are about to dissect him in a genetic experiment. What is the purpose behind this operation and how will this assist them in their enslavement of the Universe? Time is running out for the Doctor who must find a solution to this problem before he ends up on the operating table and undergoes a fate worse than death.

The Sontaran Experiment:
The Doctor (Tom Baker) and crew finds a group of shipwrecked astronauts lured by a fake distress call from an alien conducting gruesome experiments on human physical and mental endurance as a prelude to an invasion of Earth!
