Hidden among the Sumava forests lies a village that lives its own life. It is there that a young investigator heads to shed light on the death of a girl deep in the woods. Everything points to an accident. But then news of another dead body arrives, this time with clear signs of foreign involvement. The Day of the Dead, All Souls' Day, is approaching, but the circumstances lead the investigator much further back in history. Samhain. An ancient Celtic festival that opens the gateway between the worlds of the living and the dead. Is this just a coincidence, or were the bodies found here the victims of a ritual? And who is the performer?
