1976: Two young journalists leave for the French-Swiss border to investigate a strange case of cattle mutilations and record testimonies for a TV channel. Yet, once they get there, the scientific team they were supposed to meet has gone missing. Escorted by a first-aider, a British biologist and an American forensic investigator, Melissa and David go looking for the missing team deep into the mountains; but their rescue mission soon turns into a fight for survival as they get caught in an avalanche. Lost in the wild and petrified by the cold, the team experiences the ruthlessness of the mountains. They realize that blizzards, frostbite and cliffs are not that bad once they find out that they are not alone in this snowy forest.
