First broadcast on BBC1 in 1968, The Dominators sees the TARDIS materialising on the planet Dulkis, currently under threat from two alien Dominators and their robotic servants, the Quarks.

Their intention is to turn the planet into a raidoactive mass, fuel for their space fleet.

The pacifist Dulcians refuse to retaliate, until the Doctor, Jamie and Zoe arrive.

Can they help save both the planet and its people in time?

Patrick Troughton stars as the Doctor, with Frazer Hines as Jamie. Wendy Padbury, who plays Zoe in the episodes, also provides linking narration and, in a bonus interview, recalls her time in Doctor Who.
