Jacob Quisle is a formidable executioner from the ancient Bavarian town of Schongau. It is his hands that administer justice. The townspeople are afraid and avoid Jacob, considering the executioner akin to the devil... In the fall of 1668, evil spirits took possession of the glorious city of Bamberg. First, human limbs began to nail to the banks of the river, then disfigured corpses appeared on the streets... And recently, people saw an unknown wild beast scouring the night lanes... Werewolf, not otherwise! And panic swept the city. The smoke smelled in the air of bonfires threatening to incinerate any unfortunate person accused of aiding the devil. But Jacob Quisle, who arrived with the family in Bamberg on the occasion of the imminent marriage of his brother (also a local executioner), is not afraid of werewolves. He and his daughter Magdalena will have to deal with this "unclean" case and prevent new executions by the "judgment of faith" - human sacrifices arranged by people in the name of their own fear and ignorance...
