The Master arrives on Earth at a circus run by a man named Rossini and steals a dormant Nestene energy unit from a museum. He reactivates it using a radio telescope and uses his hypnotic abilities to take control of a small plastics firm run by the Farrel family, where he organises the production of deadly Auton dolls, chairs and daffodils. Humanoid Auton dummies distribute the daffodils - designed to spray a suffocating plastic film over their victim's mouth and nose - by giving them away free to members of the public in a fake promotional campaign. The Master plans to activate the flowers with a signal from the radio telescope, which he will then use to bring the main Nestene Consciousness to Earth. The Doctor manages to persuade the Master that the Nestenes will have no further use for him once they arrive. The two Time Lords then work together to send the Consciousness back into space.
