After a young cop gets involved in his third shooting, he is recruited into a special police unit. He quickly learns that the unit is an assassination corps for hoodlums and they don't care who gets in the way. Saving the life of a child gets him a beating by the unit, which they call an initiation. When they raid a mobster's home and start killing hoods and call girls who just happens to be there, he draws a line when he finds one hiding in a closet. He then goes on the run with her with gangsters and the cops both in pursuit.

Follows the journey of John and Colt, gunfighters and sometimes lovers, on parallel but very different journeys through an underground dueling culture.

A hotel room shootout between two assassins kicks off a long night of bodies falling like dominoes, as we follow a chain of crooked cops, gangsters, hitmen, a femme Fatale and an ex-mercenary through a confluence of murder, betrayal, revenge and redemption.
