The film follows writer Jean Williams as she travels to an Eskimo settlement to find inspiration for her novel. The locals are wary of "Swift Lightning", a half dog-half wolf that leads a vicious wolf pack. Jean stays behind with trapper Gaston Rogers, while the rest of the village departs on a boat. As winter worsens, Jean and Gaston are forced to leave, but she insists on taking a detour to see the annual ice-break, which puts them in danger. The story takes a romantic turn as Jean, Gaston, and the animals - including Swift Lightning, Firefly, and Buck - develop complex relationships.
