On the Polar ice-cap, 640 kilometres north of the Arctic Circle, the deadly, icy winds can freeze a man to death in minutes. But the survivors of the crashed airliner are lucky, they are rescued by three scientists from a nearby weather station. But why did the airtiner crash in the first place ? Who smashed the radio to pieces ? And why does the dead pilot have a bullet hole in his back ? The rescue quickly turns into a nightmare : a race through the endless Arctic night, a race against time, cold, hunger, and a killer with a gun.
