Bronc Burnett, pitcher for Sonora Nevada's Junior Legion team, is a champion and belongs to a champion team. Having won a New York competition, he looks enthusiastically forward to the homecoming game in which, he believes, Sonora will be pitted against a major team. When he learns that it is Spur, a neighboring town, they will play, he is bitterly resentful and makes his feelings public. From then on the two usually friendly towns become enemies, there is bitter animosity between the two teams, morale drops among the Sonoras, and finally Bronc's friends and fans turn against him. This rejection hurts the young athlete, but from his pain he gains a new dimension, basic to all top athletes. He becomes a humble and cooperative human being. Lots of technical ball talk and a run of the mill story of a boy with a bat add up here to just another run around the diamond.
