Former car thief Jimmy Kilmartin (David Caruso) ends up in jail after accompanying his cousin Ronny (Michael Rappaport) on a truck-stealing job. A cop, Calvin (Samuel L. Jackson), is wounded, and Jimmy takes the rap. While Jimmy is inside, Ronny is killed by gangster Little Junior (Nicolas Cage). When Jimmy is released, the District Attorney asks him to go undercover in Little Junior's club in an attempt to put Little Junior behind bars. Just to complicate matters, Jimmy's police 'minder' turns out to be none other than Calvin.
