On the Polar ice-cap, 640 kilometres north of the Artic 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 airliner 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 Artic night, a race against time, cold, hunger - and a killer with a gun.
