December 5 will never be the same. St. Niklas, Huub Stapel, is not the benevolent figure children are told about. He is a cruel, bloodthirsty bishop who, whenever there is a full moon on December 5, rises from the dead to slaughter as many children as possible. He travels with a gang of robbers and thieves across the countryside in the middle ages, raping, plundering and killing. When a desperate village people decide they’ve had enough, they set the ship on which he travels ablaze, murdering him and his thugs in a fiery blaze. Yet Niklas swears revenge, and the legend says that each time a full moon returns on December 5—roughly every 36 years—he and his helpers will come back to haunt the living.
The story shifts to Amsterdam, Holland, on a misty, snowy December night. Frank, Egbert Jan Weeber, a kind 17-year-old, and a group of friends are suddenly faced with the terrifying presence of Niklas and his henchmen. Frank is the only one to escape the massacre as his friends are murdered before his eyes. When the authorities question him, the police don’t believe his account and arrest him as the prime suspect, turning a night of fear into a bitter accusation.
As the pursuit intensifies, Niklas makes a dramatic escape on his fiery white horse, ducking through the canals and leaping across the rooftops of Amsterdam’s canal houses. Frank manages to break away from both the police and Niklas and finds an uneasy ally in Goert, Bert Luppes, a detective who has been suspended after he previously unraveled the Niklas mystery and warned that the evil would return this year. The two outsiders—one seeking truth, the other seeking a way to stop the nightmare—form an unlikely alliance.
The plan they devise is stark and dangerous: to blow up Niklas’s boat, moored in a remote corner of the Amsterdam Harbor, and end the threat once and for all. Their mission is not just a fight against a revenant but a test of courage, trust, and resolve in a city that has its own rituals and legends to contend with. The tension builds as the full-moon curse circles back every few decades, and the night becomes a battlefield where survival hinges on wit, nerve, and a willingness to confront the darkness head-on.
SINT unfolds as a spooky thriller loaded with action and horror, a story that invites both fans of the Saint Nicholas myth and newcomers to feel the primal struggle between good and evil. It’s a chilling ride through weather-beaten streets, shadowed corners, and a city that seems almost as haunted as the legend itself. If you’re drawn to atmospheric suspense, this tale delivers dread, momentum, and a final reckoning that lingers long after the credits.
