Jobless sportswriter Eddie Willis is hired by tainted fight promoter Nick Benko to promote his own current protégé, an not known Argentinian boxer named Toro Moreno. Even though Moreno is a giant, his own chances for victory are exacerbated by a powderpuff punch and also a glass jaw. Exploiting Willis' reputation for integrity and standing in the boxing community, Benko arranges a series of fixed fights that propel the Moreno to no 1 contender for the championship. The champ, the Buddy Brannen, guarantees to punish him and harbors bitterness. Eddie must now decide whether or not to tell the truth to the innocent Toro.
