Young and wild, George Bell lives with his rancher father, Thomas Bell, in Paradise Valley, California. When George sells his father's favorite horse, Mr. Bell turns him out, and George becomes a grain salesman in St. Louis. Meanwhile, Polly Martin lives with her father Bill, an ex-businessman who has sunk to day-labor because of his addiction to alcohol. Bill frequently abuses Polly, and when he falls to his death from a high girder, Polly becomes a nurse in the Salvation Army in St. Louis. George falls in love with Polly after he saves her from the advances of a drunk, but she will not marry him because of his wild past. Instead, she applies for a job in Paradise Valley as a nurse, where she renders aid to Thomas Bell, who has broken his leg. She nurses him back to health at his ranch, and he grows fond of her. Eventually, George learns that Polly is in Paradise Valley and follows her to the ranch.
