Terry McCann, an ex-boxer who has served a prison term is working for dodgy car salesman Arthur Daley. Alfie Cavallo, a friend of Arthur's, asks for the loan of Terry's services when he goes to collect the takings from one of the laundrettes he owns. However, Alfie and Terry walk in on an armed robbery by a trio who claim to be the Independent Rastafarian Army. Alfie is shot and the two men are taken hostage along with elderly customer Mrs. Mayhew. An overnight siege takes place. Because of his form Terry is suspected by the police of being an accomplice but he proves himself to be the hero of the day with Mrs. Mayhew vouching for the fact that he defused a very dangerous situation. Arthur is hopeful that he can make money by selling Terry's story to the press and foresees the start of a beautiful friendship.
