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.

Based on Joe Hill's novel of the same name, NOS4A2 tells the story of Charlie Manx, a seductive immortal who feeds off the souls of children, then deposits what remains of them into Christmasland – an icy, twisted Christmas village of Manx's imagination where every day is Christmas Day and unhappiness is against the law. Manx finds his whole world threatened when a young woman in New England discovers she has a dangerous gift.
