Don Raymonde Aprile's retirement from organized crime is seen as a business opportunity by his last Mafia rival. It is viewed with suspicion by Kurt Cilke, the FBI's special agent in charge of investigating organized crime. As Cilke mounts his campaign to wipe out the Mafia once and for all, Aprile finds himself in the midst of one last war, a conflict in which it is hard to distinguish who, if anyone, is on the right side of the law, and whether mercy or vengeance is the best course of action.
