Tainted fight promoter Nick Benko hires jobless sportswriter Eddie Willis to promote his own existing protégé, an not known boxer named Toro Moreno. Although Moreno is actually a giant, his own odds for victory are actuated by a powder-puff punch and a glass jaw. Exploiting Willis' reputation for integrity and standing in the boxing community, Benko arranges a set of fights that propel the unsophisticated Moreno to #1 contender for the championship. The stereotypical Buddy Brannen, the champ, promises to punish him in the ring and harbors bitterness. Eddie must now choose whether to tell the very fact to the innocent Toro.
