Contrived story surrounds a woman who is being blackmailed by a ship's captain who has killed her father and threatens to kills her ailing husband. She's saved by a dog. This is lifted a level above most of its ilk by the quality of its dark, harsh vision: from the first, we're in an arctic canada wher ruthlessness is the rule, as a dog's owner is killed in a bar for no reason (except that he's a "chinaman") much to the amusement of the bar's denizens. Good atmosphere.
