In the remote town of Blackwater, a creeping plague has decimated the population, leaving only bloodstains and terrifying signs of struggle in its wake. No bodies are ever found, only haunting traces of those who vanish. Claire, a determined doctor, arrives to investigate, dismissing the townspeople's tales of an ancient curse beneath their feet. But as blood begins to seep through the town itself, and whispers echo from the darkness below, Claire realizes the nightmare is far more real than she ever imagined. Beneath the crumbling chapel lies an unspeakable horror, waiting to claim its next victim.
