Umluk, an Eskimo chief, falls into a crevice while hunting and is rescued by Dr. Wells, a distinguished Arctic explorer and scientist. Umluk returns to his igloo, where he finds Mike Burke, an ex-whaler who runs a trading post in partnership with Izzy Hawkins. Mike has been attempting to win the favor of Umluk's promised bride, the Eskimo-Russian Wamba, by giving her trinkets. Umluk forces Mike to leave, but the trader returns later and takes the willing Wamba away with him, forcing her sister, Nootka, to accompany them as their servant. Umluk learns of the betrayal from Izzy and pursues the party in a light sled. He soon catches sight of the three travelers, but an unlucky accident to his sled prevents him from reaching them. Umluk eventually finds the group in a rough settlement, and, after several trials and tribulations, returns to his icy home with the faithful Nootka, leaving the degraded Wamba behind.—AFI
