Itauk the Madman has spread death to the Yukon, throwing the bodies of his victims to his sled team of twelve wolves. Tracking him down are Canadian Mountie Tommy McKenna and his partner Simmons. But when the pair separate to hunt for food, Itauk attacks Simmons and lets his wolves make an unmentionable feast that Tommy later discovers on his return to camp.
Enraged, Tommy follows the maniac's trail to a village and en route he meets an enchanting Eskimo woman named Kaja. Of course, the route's a trap set by Itauk, and the only one who can save Tommy is Kaja-- engaged to be wed to the ruthless killer, who plans to serve the Mountie as the next meal for his personal wolf pack.
