Upper middle class employee Tom ventures into a derelict squatter building to buy a gun from D, a cocky but stupid, homeless crack-junkie, who meanly tries to extort above the agreed price. As D stole the gun from his macho dealer Ray, the bully is on the warpath to get it back by beating up all his pushers in turn and order them to get it, anyhow. Tom's attempts to reason with Ray or buy off his wrath only get him seriously abused. He and D gradually get to know what makes the other tick and digress for reasonable life.
