Even though Tom Mix forsakes his cowboy hat for a fur cap in this Northwoods tale, the story (adapted from the novel by Frank Williams) sounds very similar to any number of Westerns. When the father of Donald MacTavish (Mix) is appointed commissioner of the Hudson Bay Company, trading post head Angus Fitzpatrick (Frank Clark), who wanted the job, is furious. He takes out his enmity on Donald, who is in love with Fitzpatrick's daughter, Jeanne (Colleen Moore, still a few years off from stardom). He accuses Donald of stealing a large quota of furs, but the culprits are actually a group of dishonest traders, led by Sergius (Sid Jordan). Sergius is also in love with Jeanne, and he kidnaps her. Donald goes to her rescue and in spite of the thieves' best attempts to stop him, he saves her. Donald and Jeanne go back to her father, Fitzpatrick, who has been injured while tussling with the bad guys. Fitzpatrick become friends with Donald, who gathers together a posse and rounds up the thieves.
