Blutmond

The sun will turn to darkness and the moon to blood. Nocturnal knocking sounds that seem to come from everywhere, bloody handprints appearing out of nowhere, and badly mutilated corpses discovered in the morning: a small town on the North Sea is being terrorized by mysterious murder cases. During a full moon. But when former commissioner Richard Winter begins the investigation, he encounters only rejection and hostility from the locals. He discovers that the haunting began exactly one month after a blood moon. He quickly realizes that there is much more going on than he was initially led to believe. And as the next full moon approaches, he suddenly finds himself fearing for his life... Former commissioner Richard Winter, specialized in mysterious crimes, investigates his second case, in which a seemingly invisible and cruel murderer is at large.
