As a ferry carrying 300 passengers from Denmark pulls into an Icelandic town s small port, heavy snow begins to fall. The ferry can t leave until the storm passes and the main road into town is impassable. A mutilated and dismembered body washes on the shore, an unidentifiable man murdered only hours ago. The local police chief, Andri Olafssun, whose personal life is in shatters, realises a killer has descended into his town. As word spreads, order disintegrates into chaos as the ferry s passengers and the town s residents realise they are all possible suspects and that a killer is trapped among them.
