1222 metres above sea level and the worst snow storm in recent Norwegian history is raging. A train on its way to the northern reaches of Norway careens off the track. The passengers abandon the train for a nearby, centuries-old hotel that is practically empty except for the staff. With plenty of food and shelter from the storm, the passengers think they are safe--until one of them turns up dead. With no sign of rescue and the storm continuing to rage, retired police inspector Hanne Wilhelmsen is asked to investigate.
