“When a Klan leader is murdered, it lights the fuse to a race explosion. Now the only man who can put it out is the one everyone suspects.”

Jim Natter, the leader of a violent Ku Klux Klan lodge, is shot dead. His teenage son Eric Natter is found nearby, and taken into police custody for his protection pending the investigation. While four cops drive him to a safe-house, they are ambushed. Three of them shot dead, including Deputy Lawrence, and his black partner Jerry Robinson is accused of the murders.
