After their boss is killed during a bank heist, London gangsters Brian Hope (Idle) and Charlie McManus (Coltrane) desire to lead more peaceful lives in Brazil, disapproving of their new younger and more brash boss, Casey (Patterson). While planning to rob a local Triad gang of their ill-gotten drug money, Brian meets and falls in love with a waitress, Faith (Coduri). During the robbery, Brian and Charlie betray their fellow gangsters, Abbott and Morley, steal the money and flee, but are forced to abandon their car when it runs out of petrol and seek refuge in a nearby nunnery during the ensuing gunfight. Faith, who had tried to warn Brian beforehand, is shot in the wrist by Abbott, while one of the triads is shot and hospitalised. After this, Casey places a bounty on Brian and Charlie's heads.
