George Bell, a wild young man, 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.
