Paleontologist Kate Lloyd has traveled to the desolate region for the expedition of her lifetime. Joining a Norwegian scientific team that has stumbled across an extraterrestrial ship buried in the ice, she discovers an organism that seems to have died in the crash eons ago. But it is about to wake up. When a simple experiment frees the alien from its frozen prison, Kate must join the crew's pilot, Carter, to keep it from killing them off one at a time. And in this vast, intense land, a parasite that can mimic anything it touches will pit human against human as it tries to survive and flourish.
