Zoe's quantum duplicate is transported to the Tibari President's spaceship, where she is taken to meet the President, Ram Vendl. Atrekar delays the assassination, hoping for maximum impact. Vendl befriends Zoe, but keeps her in detention for security. Meanwhile, in Atrekar's facility, the Daleks take over. They decide to test Atrekar's mind projector, using the Doctor as a test subject. A duplicate of the Doctor is transported to the Tibari ship, but Atrekar cannot control him. When Atrekar attempts to activate Zoe as an assassin, the Doctor prevents her from killing Vendl. Frustrated, the Daleks use the mind projector on themselves, and Dalek duplicates arrive on the ship. However, Atrekar has realized that the Daleks do not plan to keep their agreement with him, and uses his telepathy to take over one of the Daleks. He turns the Daleks' own worst fears against them, and they are destroyed. Jamie activates a switch which restores the Doctor and Zoe to their own bodies. The Doctor destroys the mind projector, and the peace talks proceed as scheduled.
