A winter trip to Alaska becomes a nightmare when Bret and his friends venture deep into the Brooks Range, unaware that a starving clan of Tornit — intelligent, primitive, and desperate — has been forced south in search of food. When a young Tornit girl is accidentally struck and killed by a snowmobile, her father’s grief turns into a rage that nothing human can outrun. As the blizzard closes in, the men fight to escape a creature driven not by hunger, but by vengeance. Bret is the only one who makes it out alive, half‑frozen and terrified, whispering the warning the others never lived long enough to understand: they can feel your footsteps.
