After the death of several protesters in the mountains of Dovre, the Norwegian government seeks the help of a paleontologist, Nora Tidemman, who teams up with the prime minister's advisor Andreas, and Norwegian military soldier Kris. The three seek assistance from Nora's folklore expert father, Tobias, who in the past lost his job for his belief in the existence of mythical creatures such as trolls. The group determines a troll is responsible for the death of the protesters and ought to stop both the creature from wreaking more havoc and their government from exacerbating the situation.
