After the death of his parents, struggling American novelist Ohm Bauman (Adam Scott) travels to a secluded countryside inn in Ireland to honor their final wishes by scattering their ashes. The hotel, once a romantic destination where his parents honeymooned, is steeped in eerie folklore and shadowed by a troubled past.

Seeking solitude and inspiration, Ohm becomes increasingly unsettled as he encounters a cast of enigmatic guests and tight-lipped staff. When a guest mysteriously disappears, he is drawn deeper into the inn's sinister history and the possibility that its legends may be more than mere superstition. As he becomes entangled in local tales of a witch said to haunt the hotel's forbidden bridal suite, Ohm experiences terrifying visions that blur the line between reality and nightmare, pulling him into a confrontational and nightmarish mystery.
