Mariaseeon, in the south of Munich: Agnes is actually looking for peace and distance in the tranquil community after a tragic blow of fate shook her life a year ago. But then a five-year-old boy disappears without a trace, and the village is thrown into panic. After days of searching, Jakob is found naked, bound, and traumatized on a pile of wood in the forest. However, the relief is short-lived, as shortly after, the brutally mutilated body of his caregiver is discovered. A biblical scene of sacrifice, a murder in the style of the Inquisition – fear spreads among Agnes and the other villagers. One of them is a sadistic murderer, and Commissioner Konstantin Dühnfort must find him before he strikes again.
