Howland is a trapper and is supremely happy with his wife, Jeanne, and son, Robert, in their cabin in the north. Blake, a trader, also married is traveling to the nearest trading post. Out with Robert for a sled ride, Jeanne runs her sled into a snow slide, and, but for the timely assistance of Blake, both would have been killed. Jeanne escapes unhurt, but Robert suffers injuries which necessitate an operation. While Howland takes the boy to the nearest doctor, Blake is left to look after Jeanne. In the lonely nights which follow, Blake wins her love and when Howland returns with his son, now recovered, he finds the cabin empty. Howland vows to be avenged on Blake. After some time, the latter tires of Jeanne and leaves her to return to his lawful wife. At home, he finds his three young sons in tears over their mother's death. Sorrowful now for his treatment of Jeanne, he returns to the cabin where he left her but finds that she has already gone.
