A German Shepherd puppy is "adopted" by a wolf pack in the snowy and frozen Great North and raised by them as one of their own. A few years later he comes upon a fur trapper and saves the man from certain death, and begins to feel a kinship with him that is stronger than the one he has with his adopted pack.

Although he loves his childhood playmate Marcelle Riley, Luke Halliday, whose father made his fortune as an Arizona miner, becomes engaged to Eleanor Steele, a New York high society girl. When Scar Norton arrives from Arizona and reveals that Luke's mother was Indian, Luke is so traumatized that he breaks off their engagement and ventures west to live among his mother's people.
