The Bloodhound (1925)

"Moose" Rambo is killed by an unknown assailant during a barroom brawl, and Belleau is wrongfully accused of the crime. Sergeant McKenna of the Northwest Mounted Police is detailed to go after him, and Constable Fitzgerald, who saw Belleau on the night of the murder, is struck by the resemblance between Belleau and McKenna. Believing them to be the same man, Fitzgerald confides his suspicions to the chief and is detailed to pursue McKenna. McKenna tracks Belleau and learns that he is his own twin brother. Fitzgerald tracks McKenna, and McKenna, in order to protect his brother's wife and child, allows himself to be arrested as Belleau. Belleau's wife, who quickly sees through the deception, eventually tells the police that they are holding the wrong man. McKenna is freed and again tracks down his brother, bringing him back to stand trial. The real murderer, a half-breed, has confessed, however, and Belleau is freed. McKenna marries Marie Rambo.
