Wally Bristow is a wealthy young chap infatuated with a heartless society girl. He discovers that she is not true to him and leaves her. At the club he runs into an argument among the members to the effect that none of them could start out with nothing and return in a year, married and successful. Wally takes his friends up on the bet. Wally goes west and secures employment on a ranch. He becomes the butt of the cow punchers jokes, and his employer's daughter thinks him a prig until, one day, she observes him thrash a ranch bully for ill-treating a dog. Soon after she promises to be his wife. The society girl, meantime, hears of it and starts west to break up the match. Arriving in the neighborhood she sends a note to her rival saying that the man is untrue to her and to go to a certain place and she will see him with another woman. The ranch girl does this and sees her sweetheart with another woman. There is a quarrel, but the fiancée, just before Wally is about to return finds her mistake. She overtakes Wally at the station; there is forgiven and the two hoard the train for the east. Wally wins his bet.
