The Doctor is surprised to find that the mercenary Lytton is on Earth and apparently in league with the Cybermen.

Vengeance on Varos

The Doctor and Peri visit the mining planet of Varos, in order to pick up some Zyton-7, a rare compound needed by the TARDIS. The inhabitants of Varos enjoy watching criminals being publicly tortured and executed, and punish unpopular decisions by direct pain control by the Governor! The Doctor discovers that Sil, a small and obnoxious reptile from Galatron who is supposed to be negotiating a trading arrangement with the Governor, is in fact plotting to take over Varos to gain total control of the Zyton-7 supply!

Mark of the Rani

But what is their real motive in being on Earth at this period in it's history?

The Two Doctors

The Doctor and Jamie are sent by the Time Lords to visit a scientific Think Tank in deep space, they helped establish, to protest about the dangerous time travel experiments being carried out there. It turns out to be a trap and the Doctor is caught. Later the (other) Doctor and Peri arrive to investigate the disappearance of the Doctor and Jamie, and are re-united with Jamie. Their investigations lead them to Earth where the Sontarans are backing a megalomanic scientist's dangerous experiments into time travel and genetic engineering.


The Doctor and Peri are startled to a see the image of a girl fly through the TARDIS console room. They discover a time tunnel, and trace it back to the planet Karfel, where they find that a cruel tyrant, the Borad, throws his opponents into the time tunnel. The Doctor is forced by the Borad to retrieve the girl Vena, who fell into the time tunnel with a vital amulet, and finds that the far end of the tunnel is in 19th century Scotland! Bringing back Herbert, a young man vacationing in Scotland who enters the TARDIS accidentally, and Vena, the Doctor must return to Karfel to defeat the Borad, who is revealed to be a weird mutant!

However, Tranquil Repose is not all it seems and an attempt is made on the Doctor's life.
