Wolves of the North is a 1924 American Northern drama film serial directed by and starring William Duncan.

[1] The working title was The Free Traders and the film featured a polar bear cub named Pluto.

Pluto had been “captured by a whaler" and ended up at Los Angeles Harbor where he was acquired by the Universal City Zoo.

[2] As described in a film magazine,[3] Alan Gray (Duncan), free trader, beats up Dan Martin (Rice) and Pierre DuPre (Bonomo), fur pirates, who accuse him of poaching.

Dan and Pierre rescue Bob from the lockup, steal Madge's furs, take Helen (Johnson), the daughter of Grimwood Mears, and, pursued by Alan, canoe down the rapids.

Alan rescues Helen Mears from the wolves and goes on to Eagle Bird's tepee, where he trades for the Indian's furs.
