Rising boxer Jimmy Kane from New York City is sent to the Rosario Ranch and Hot Springs in New Mexico to regain his health after spending too much time with women and drink. There, he meets young widow Peggy Harmon and her son Dickie Harmon, and a gentle affection blossoms between them. Peggy gradually falls for him, and he finds himself drawn to her as well. When Jimmy learns that Peggy will have to cut short her son’s treatment because there’s no insurance payout, he resolves to do whatever it takes to help: he travels to Tijuana to take on a tough fight that can raise the $600 she needs. The scars on his face become a visible reminder to Peggy of the price he’s paid for their future, and the sacrifice deepens their bond.
Returning to New York, Jimmy’s path intertwines with high society for the first time when he is introduced by Roger Elliott to the flighty, stylish Joan Gibson. He quickly falls for her, mistaking her interest as true love, while his career and ego begin to blur into ambitions he hadn’t anticipated. His manager, Pop Slavin, hints at a championship opportunity, but Jimmy chooses a different course: he privately goes to a plastic surgeon to correct his nose and cauliflower ear after Joan points out that he would be handsome if not for those features. He also takes etiquette lessons from Forbes to refine his manners and image, hoping to win Joan’s respect and admiration. When he surprises Joan with this transformed self, she reacts with irritation, telling friends that he’s lost his color and individuality.
Jimmy’s decisions echo through his circle as his style changes from raw power to more controlled, boxed-in precision—aimed at protecting his new face. The crowds react with boos, sensing a different, less colorful fighter. Meanwhile, Peggy remains a constant, and Jimmy begins to grapple with the ache of a romance he’s chosen to delay for the sake of appearances. He asks Pop to field matches against lesser opponents to rebuild his standing, but offstage the strain of his two worlds weighs heavy. He tells Peggy that he’s seeing someone else, a confession that strains their fragile hope for a future together.
As the championship fight approaches, Jimmy resolves to one last bid for glory: win the title and then marry Peggy. He sends ringside seats to Peggy, hoping she’ll be there for the victory—and the vow. On the night of the fight, though, Joan’s absence unsettles him. He sends Rosebud, the loyal trainer, to locate her, and the tension mounts as the bout begins with Jimmy avoiding direct contact in the opening rounds. Word comes that Joan plans to sail away on an ocean liner within minutes, adding a cruel, time-bound edge to the drama.
In a burst of ferocity, Jimmy overturns the cautious plan and delivers a knockout to the reigning champion. He races to the pier by taxi, determined to confront Joan before she vanishes. When he finds her, she lies that her sister needs her, but the truth surfaces only when Roger Elliott enters the cabin, revealing the real situation behind Joan’s deception. Enraged, Jimmy confronts the double betrayal—he punches Roger Elliott and then strikes Joan when she bends over the unconscious man. The storm finally settles as Jimmy, bleeding and breathless, declares his intention to marry Peggy, solidifying a future built on sacrifice, passion, and a hard-won resolve.
