The Master re-establishes psychic control of his robot slave Kamelion. He wants to hijack the Doctor's TARDIS to reach the planet Sarn, where he seeks the healing power of Numismaton Gas to restore himself. Once on Sarn, Turlough comes face to face with his destiny.
A strange signal from Earth draws the TARDIS to the island of Lanzarote, where Turlough rescues a young American girl, Peri, from drowning. Among her possessions is an artefact bearing an alien symbol - the same triangular mark that Turlough has branded into his arm. The mystery deepens when Kamelion falls under the control of a powerful mind, and the TARDIS travels to the volcanic world of Sarn. As Turlough is forced to face his past, the Fifth Doctor must stop his oldest enemy from harnessing the revitalising powers of Numismaton gas...
The plot is set on a group of bank robbers, who are both violent and successful, strangely getting away each time with an amount around the £60,000 mark, and often leaving behind cash in excess of this sum. The robbers are willing to kill their own team, to get away. As Jack Regan himself puts it after the first raid in the film: "I've never seen so many dead people". Armed with gold-plated Purdey shotguns, they evaded Regan and the Flying Squad for quite some time, before Regan finds encouragement from his Detective Chief Superintendent who was sent down for corruption because Jack wouldn't testify in court for him.
When one of Regan's snouts complains that his girlfriend's recent suicide was murder, the flying squad detective feels compelled to investigate. He uncovers a conspiracy that reaches the heart of the government, and finds himself fitted up, suspended and under the scrutiny of Special Branch.
