London gangster Willie Parker gives evidence against his criminal compatriots in return for a very generous offer from the police. Ten years later, Parker is living in comfortable retirement in Spain. Four Spanish youths kidnap him and deliver him to British hit man Braddock and his sidekick Myron, hired by the kingpin that Parker helped put away. In the course of the kidnapping the youths run down a Spanish policeman who has been assigned to guard Parker. Three of the youths are then killed by a bomb in a briefcase, which they believe to contain their pay-off, handed to them by Braddock. Braddock is a world-weary professional killer while Myron is his perky but volatile young apprentice. Parker quickly adopts a carefree demeanour, later explaining that he’s had ten years to accept death as a simple part of life.
