Underworld on AllMovie

In this Quentin Tarantino-style blood-drenched pseudo-film noir, Denis Leary plays a hood named Johnny who, after getting out of prison, dedicates himself to exacting revenge on mobsters who brutally injured his father. Ned Lynch (Larry Bishop, who wrote the screenplay) attacked Johnny's father, causing him to become permanently brain-dead. Johnny travels in a limousine and targets those who he believes may be responsible in a series of killings that take place on Father's Day. His main target is Frank (Joe Mantegna), but he is not certain that Frank is responsible for what happened to his father. Johnny, who has taught himself psychology in prison, takes Frank to a sex therapist, Dr. Diane Leah (Annabella Sciorra), as part of his cat-and-mouse game, in hopes of eventually learning the identity of his father's attacker.
