Railroad president John Houston, along with his daughter Marjorie and his fiancee, Elinor Craig, are aboard the express train when it is held up by a gang of outlaws. Outlaw Dan Tracy is attracted to Marjorie, who, filled with dreams of romance, returns his interest. They exchange rings and later meet secretly in the city. When Houston learns that his daughter’s new suitor is an outlaw, he hires a detective to investigate. The investigation indicates that Tracy is Houston’s son by a former marriage, and Houston, mortified, allows the outlaw to escape. Tracy then persuades Marjorie to elope with him and takes her to his shack in the hills where she is rudely awakened to the realities of outlaw life. Houston arrives to save his daughter, and after Tracy is killed by Rosanne, the woman he betrayed, it is revealed that Tracy was not his son but an offspring of his former wife and an outlaw.
