In an eerie Austrian village, a young American named Peter returns to his ancestral home, a crumbling castle soaked in the legends of its gruesome past. Joining him is Eva, a local historian. Intrigued by the dark tales of Peter's ancestor, the sadistic executioner Baron Otto von Kleist, they unwittingly discover an ancient incantation rumored to summon the Baron's vengeful spirit. Despite initial skepticism, they decide to perform the ritual, seeking a thrill and never believing it could actually work. Much to their horror, the bloodthirsty Baron is resurrected from centuries of dormancy, immediately resuming his reign of terror upon the village.

Struggling to contain the nightmarish consequences of their actions, Peter and Eva race against time to find a solution, delving deeper into the occult and uncovering more dark secrets of the castle. As fear grips the village, the line between legend and reality blurs, leaving the pair to confront not just supernatural horrors but the haunting legacy of Peter’s lineage. They must navigate a perilous path filled with unexpected allies and enemies, grappling with complex emotions and moral dilemmas, as they seek to undo the terror they have unleashed.
