True Convictions (1991)

Synopsis
The son of an Italian mobster, John Laguna is highly ambivalent about his involvement with that life, but so far he has only served as a debt collector. When his father tells him he must kill his best friend because he is a "rat" (informer), it creates a real crisis in his life. His father is forced to use some devious means to induce him to carry out the mob's traditional form of justice and at the same time become a "made" man. ~ Clarke Fountain, All Movie Guide
