The movie opens with a woman (Ane Dahl Torp) being chased through the snows of Norway. She is finally cornered and eaten by zombies in World War II German uniforms. The movie then moves to seven medical students on Easter vacation. They arrive at a small cabin near Oksfjord, about a 45minute walk from the road where they have left their cars. The cabin is owned by Sara, another student who is the girlfriend of Vegard (Lasse Valdal), the student in the main group with the most knowledge of the wilderness. She has been skiing across the mountains to meet them, but has not yet arrived.
