Miners Bucky Malone and Pierre Le Grande are closing their northern mine for the winter when Sergeant McClellan of the Mounted Police overhears their trivial quarrel; later, he sees Le Grande's dogsled arrive at its destination without Le Grande. McClellan finds evidence that Le Grande has been murdered and suspects Malone; attempting to make an arrest, the sergeant is wounded, then carried to a cabin by Malone, who goes to the settlement for a doctor. There he meets Le Grande's daughter, Joan, and Dr. Chambers, a disbarred physician, but a blizzard keeps the doctor from making the trip; ultimately, however, Joan and the doctor follow Malone to the cabin.
