River's End
In remote northern Canada, Sergeant Conniston (Bickford) seeks to capture escaped convicted murderer Keith (also played by Bickford). He is accompanied by O'Toole (J. Farrell MacDonald), a guide who is constantly drunk. When he finally catches his quarry, he is shocked to find that they look exactly alike.
On their way back to the RCMP post, however, their sled overturns. Keith takes Conniston's gun and sled and leaves the policeman and his guide to die in the snow. Keith starts to feel guilty about what he has done. He turns back and takes the men to an emergency cabin. In spite of this, Conniston dies of a frozen lung.
After talking to Keith for a while, O'Toole becomes convinced of his innocence. He coaches Keith so that he can pass himself off as the sergeant. O'Toole is not well enough to travel, so Keith goes to the RCMP post alone.
Once he arrives, Keith tells McDowell (David Torrence), the post commanding officer, that it was Keith who died. McDowell then informs him that Keith was innocent; the real murderer confessed. Worried that he will be accused of Conniston's murder if his true identity is discovered, Keith plans to escape across the border.
There are complications. Miriam (Evalyn Knapp), McDowell's daughter, had been Conniston's girl, but she decided to break up with him. Keith is very much attracted to her, and proves to be much more romantic than Conniston. Miriam finds herself falling in love with him. Mickey (Frank Coghlan, Jr.), O'Toole's young son, had adopted Conniston as a substitute father. He eventually realizes that Keith is not the sergeant, but Keith manages to persuade him to keep his secret.
Keith goes to see McDowell to ask for his daughter's hand in marriage, only to discover that a jealous rival had made inquiries. Conniston, it turns out, was married. McDowell orders him to leave the base in disgrace. Before he goes, he confesses the truth to Miriam. Then, refusing to sneak away, Keith braves a beating from a gauntlet of angry Mounties and boards a ship, accompanied by Mickey. At the last minute, Miriam boards as well.
