As described in a film magazine,[2] Square Shootin' Harry Lanyon (Carey), proprietor of a gambling hall in Arizona, is in love with his ward Ruth Watson (Hope). However, he believes that she is in love with his pal Billy Lanyon (Landis), and intends to let the youth have the girl. While in this uncertain mind about his own love affair, Harry begins to read Bret Harte's story "The Outcasts of Poker Flat" and begins to liken himself to John Oakhurst in the story. Oakhurst (Carey) befriends a girl named Sophy (Hope) on a riverboat. The girl is being deserted by a gambler named Ned Stratton (Harris), who had promised to marry her, and Oakhurst saves her from self-destruction. Oakhurst brings Sophy to the questionable neighborhood of Poker Flat, and encourages her to marry some youth who loves her, although Oakhurst also cares for her. Stratton reappears and Oakhurst makes it his business to rid the camp of him. Later, the Vigilantes swoop down upon Poker Flat and, in a reform movement, send Oakhurst, Mother Shipton, the Duchess, and others into the hills. Sophy and her young husband follow. They are all caught in a violent storm from which only the latter two emerge alive. Harry Lanyon is impressed with the Bret Harte story, and vows that he will not repeat the mistake of Oakhurst and in sacrificing his love for another. Harry then discovers that Ruth loves him and not Billy after all.
