Research scientist Tyler Farley (Charles Martin Smith) is sent to the desolate Canadian tundra to research the local wolf population and their supposed decimation of the caribou herds. Helped by Ootek (Zachary Ittimangnaq), a local Inuit native, Farley manages to establish an observation post and, while braving the harsh climate, begins to study a family of wolves, as well as the caribou. He eventually determines that the greatest danger to the caribou doesn't move on four legs.
