Orphan twins found in a snowstorm by Father Ormounde are adopted from a Montreal orphanage by an officer of the Northwest Mounted Police and Pierre Maupome, a leader of desperadoes. Twenty years later, one of them, "Bad" Maupome, has become leader of a gang of thieves, and the other, John, has become a lieutenant in the Northwest Mounted Police. John meets Patricia Graham and falls in love with her after rescuing her from a forest fire. Meanwhile, having directed the looting of an Indian village, "Bad" goes to De Brac's trading post and roughs up the trader when he objects to his seeing his daughter; however, the infatuated Rosa goes to "Bad's" cabin where Father Ormounde discloses the bandit's identity. Maupome steals a police uniform and robs and wounds Miss Graham's father. John is arrested, but he escapes and trails his brother, who is killed by a falling tree in a storm. John is cleared by the girl's testimony, and they are happy together.
