Dick Maas writes and directs this Dutch comedy horror re-imagining Santa Claus as a psychopathic child-killing zombie. Whenever a full moon occurs on the 5th of December, the bloodthirsty Sinterklaas (Huub Stapel) returns to Amsterdam to embark on another of his vicious killing sprees. But this time he faces the wrath of Inspector Goert (Bert Luppes), who witnessed Sinterklaas murdering his whole family some years before, and Frank (Egbert Jan Weeber), whose friends have only just been slaughtered. The two men join forces in a desperate attempt to put an end to the killlings once and for all.
