Juice (movie, 1992)

Four Harlem friends -- Bishop, Q, Steel and Raheem -- dabble in petty crime, but they decide to go big by knocking off a convenience store. Bishop, the magnetic leader of the group, has the gun. But Q has different aspirations. He wants to be a DJ and happens to have a gig the night of the robbery. Unfortunately for him, Bishop isn't willing to take no for answer in a game where everything's for keeps.
