Doctor Who: Day of the Daleks (TV)

Sir Reginald Styles, organiser of a world peace conference, narrowly survives an assassination attempt by a combat-uniformed guerrilla who vanishes like a ghost. Later the guerrilla is attacked by huge, ape-like creatures called Ogrons and found unconscious by UNIT troops in the grounds of the house. The Doctor deduces that he comes from about two hundred years in the future and that a device found with him is a time machine. While Styles is away, the Doctor and Jo keep watch. The guerrillas attack again, but the Time Lord convinces them that he is not Styles. One of their party, Shura, is later injured by an Ogron. Jo meanwhile accidentally activates one of the guerrillas' time machines and is transported to the 22nd Century. When the guerrillas return there, the Doctor goes with them. He learns that the Earth of this period is ruled by the Daleks with the help of the Ogrons and human collaborators, whose leader is known as the Controller. Jo and the Doctor are both taken prisoner at the Dalek base.
