Colin Diamond (Ray Winstone) is a pot-bellied British gangster happily married to Liz, his wife of twenty-one years (Joanne Whalley). The problem is she’s not happily married to him. When Liz tells Colin she’s leaving him for a lover, he slides from incredulity to rage. Marital delusions wrecked, he resorts to gangster methodology. He assaults his wife (mostly off-screen) to get the lothario’s name—a studly French waiter (Melvil Poupaud).
Colin has a four-man crew with whom he toils at their underworld trade.
