After a lifetime of mistakes, Linda is sent to serve time in Iceland’s only women’s prison for a vicious assault that leaves her father in a coma. But no-one knows that she harbours a dark secret that could tear her family apart, a secret that could set her free.
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, 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.
