Shank is a depressed lover, an ex-mob hitman who's out to avenge his murdered girlfriend, Eva. His boss, Cesar, had ordered The Butcher, Angelo, and Cassandra to kill Shank and Eva for their slip-up during the assassination of the mayor, which Cesar had perpetrated. The Butcher rapes and kills Eva before Shanks' very eyes before Angelo sets fire to the house, leaving a wounded Shank to die.

Shank survives and now seeks revenge with his blood boiling every time he remembers his dead girlfriend. His first target is the Butcher, followed by Angelo, Cassandra, and the mob leader Cesar, to make sure they pay the ultimate price for Eva's death.
