When narcotics cop Jack Walsh accidentally kills the son of Mafia boss Johnny D'Angelo in a drunken road accident his life is effectively over. But when he comes out of jail to begin a solitary existence in a small town, he finds there is no escape from the past. For D'Angelo honour dictates that Walsh is killed to avenge his son - and for the FBI, who up to now have been unable to nail the Mafia boss, Walsh is the perfect bait to pin a murder rap on him. With Mafia hit squads closing in and the FBI hoping to catch them in the act, Walsh has never been so alone - only the street cunning of a veteran cop and a small arsenal of weapons can save him.
