A young boxer fights prejudice to work with a female manager.

Cooky Bradford works as a sparring partner for the boxers managed by Pop Baldwin but wants to be a real fighter someday. He hopes to win enough money to buy the lunch wagon where he now serves hamburgers. His aspirations are shared by Pop's daughter Honey, and after Pop dies, only Cooky and trainer Schultzy agree to work for a woman when Honey decides to run the gym. Honey arranges Cooky's first fight, for which he earns a ten-dollar gold piece when he wins. The victory inspires Honey and Cooky to get married, and they keep the coin for luck. Cooky wins all of the fights in his area, and the couple leave for New York City to pursue greater challenges. In the city their luck changes, and the couple are nearly broke when Cooky is offered a fight that he cannot take because the promoters refuse to allow a woman to manage him. Cooky then returns to slinging hamburgers until Honey is able to arrange a charity bout for him. His skill is recognized, and his fame grows as he wins more fights. Cooky and Honey's happiness is sabotaged, however, by the appearance of Kay Mitchell, a wily society girl bent on winning Cooky's affections. Cooky goes into debt trying to match Kay's Park Avenue flash, and also begins to lose his edge as a fighter. He loses more and more bouts, until finally Honey accuses him of cowardice. Cooky then leaves Honey and falls in with an unscrupulous new manager, who sets him up to lose a match and all of his money. Kay breaks off their relationship, after which Cooky's life continues to spiral downward until he is again a poor, small-time fighter. Meanwhile, Honey has become a prosperous manager. Determined to help her husband, whom she still loves, Honey gets Schultzy to bring Cooky to her office. She then arranges for him to overhear her insult his ability, and he becomes angry enough to win another bout. Honey's confidence in Cooky is renewed as his fighting abilities and love for her return stronger than ever.
