Two brutal hoods put their victims through savage beatings in Bumper's (George Kennedy) district. Although preoccupied by the plight of a friend, a veteran cop wrongly accused of police brutality, Bumper keeps tracking a couple of hoods who specialize in stealing from pushers, bookmakers, and others who can't turn to the police. 

The assistant of an unscrupulous bookmaker refuses help from Bumper (George Kennedy) for fear of reprisal.
