Hammer is fired after a fight with one of Big Sid's men so he can be recruited as a boxer for Big Sid's stable.  He's warned by Officer Davis that he's being used by Big Sid whose former boxers don't live long.  When Hammer's trainer refuses to get Hammer to take a dive, he's beaten almost to death by Brenner.  Brenner  kidnaps Hammer's girlfriend Lois as insurance that Hammer will blow the fight.  As the big fight proceeds with Hammer to take a dive at the end, Davis rescues Lois.  Hammer wins the fight.  Brenner retaliates by killing Big Sid and trying to kill Hammer.  Hammer puts Brenner's head through a car window, where Brenner collapses, his face covered in blood.
