Jim Carvel, whose father Henry, a newspaper owner, has been killed by the local political boss for exposing a theft ring, shoots his father's murderer and escapes to the Canadian Northwest where he befriends Nepeese, daughter of a local trapper named Pierre. Brutal trading post owner "Bush" McTaggart attacks Nepeese while she is alone in her cabin. Pierre arrives home and tries to defend his daughter, but McTaggart kills him. To clear himself, McTaggart blames Jim for the murder, and while a group of Indians track Jim down, kidnaps Nepeese. Jim is rescued by his half-breed friend De Bar while Baree, Nepeese's dog, hunts down and overcomes McTaggart. Freed from McTaggart's clutches, Nepeese marries Jim.
