The Dominators is the first serial of the sixth season of the British science fiction television series Doctor Who, which originally aired in five weekly parts from 10 August to 7 September 1968. In the serial, the Second Doctor (Patrick Troughton) and his travelling companions Jamie McCrimmon (Frazer Hines) and Zoe Heriot (Wendy Padbury) work with the Dulcians of the planet Dulkis to prevent the alien Dominators from blowing up Dulkis and using its irradiated remains as spaceship fuel. Plot An alien craft bearing the ruthless Dominators arrives on the peaceful planet of Dulkis. The craft lands on the Island of Death, a nuclear test site housing an anti-war museum, and soon absorbs all the radiation on the island. The robotic Quarks are sent out by the Dominators to prepare boreholes into the planet’s crust in order to convert the planet into rocket fuel. Toba uses the Quarks to fire on and kill three adventure seekers who stumble across his project. Their pilot Cully, however, survives by hiding, though the craft that brought him to the island is destroyed. Rago is furious that these potential slaves have been wasted. The TARDIS arrives on another part of the island and the Doctor and his companions Jamie and Zoe hear the explosion of the craft being destroyed. They take shelter in the museum and meet three other newly arrived Dulcians, Educator Balan and his young charges Teel and Kando. All are puzzled that the radiation reading on the Island is nil, since it should be radioactive after the nuclear explosion 172 years earlier. Cully arrives too, and tells them about the murderous Dominators and their robots. Balan does not accept this: Cully, the son of the Director of the ruling council, is well-known as a practical joker. The Quarks have begun work on drilling the outer boreholes. The Doctor and Jamie are captured by a patrol of Quarks and taken to the Dominator ship for questioning and scanning. A scan of Jamie is presumed to apply to them both and to the Dulcian race as a whole, who are thus described as possible but not definite for conversion into a slave force. During an intelligence test, the Doctor feigns stupidity to prove their worthlessness. He also fails to use a weapon from the Dulcian museum, falsely claiming such military technology has been lost to the Dulcians. The Doctor and Jamie are freed
