Jobless sportswriter Eddie Willis is hired by corrupt fight promoter Nick Benko to advertise his, an unknown boxer named Toro Moreno. Although Moreno is actually really a giant, his odds for victory are hampered by a powderpuff punch and a glass jaw. Exploiting Willis' reputation for integrity and standing at the boxing community, Benko arranges a set of fixed fights that propel the un-sophisticated Moreno to no 1 contender for the championship. The reigning champ, the sadistic Buddy Brannen, harbors resentment at the promotion Toro was receiving and guarantees to viciously punish him from the ring. Eddie must decide whether to tell the very fact to the naive Toro.
