In the secluded town of Ivorton, nestled in misty mountains, a dark presence lurks. A botched exorcism claims the life of a young girl, but the villagers remain in denial, even as an eerie unease spreads. Whispers speak of a malevolent force unleashed by the girl's father, whose madness may have summoned something far worse.

Ivorton thrives in isolation, its abundant resources untouched by the drought, famine, and rotting disease plaguing the outside world. But the river, once a lifeline, is tainted — its true contamination hidden behind layers of lies and secrets. As superstitions mount, the fragile line between reality and hysteria blurs, setting the stage for a terrifying revelation with consequences far beyond the town's borders.
