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, realizes a killer has descended into his town. As word spreads, order disintegrates into chaos as the ferry s passengers and the town s residents realize they are all possible suspects and that a killer is trapped among them.
