An ex-con's first act of freedom is moving to Miami where he restarts his old criminal ways with even more potency.

Martin Blank is a freelance hitman who starts to develop a conscience, which causes him to muff a couple of routine assignments. On the advice of his secretary and his psychiatrist, he attends his 10th year High School reunion in Grosse Pointe, Michigan (a Detroit suburb where he's also contracted to kill someone). Hot on his tail are a couple of over-enthusiastic federal agents, another assassin who wants to kill him, and Grocer, an assassin who wants him to join an "Assassin's Union."
