Anna is on a scientific expedition to the North Pole, when the black of the night is lit up by a distress flare, coming from the Chinese research station. But is the flare a cry for help or a warning sign? As a blizzard rages, Anna finds herself caught in the middle of a savage international struggle for the Arctic's resources, with a killer somewhere in the dark. Can she find her way out alive? A nailbiting, claustrophobic and topical thriller set at the North Pole from Norway's most successful screenwriter.
