A group of young women visiting a supposed Elizabeth Bathory historical site in Yorkshire discover the location is actually a staged Airbnb experience that turns sinister when a double booking forces them to stay overnight. After finding a disturbing diary linked to Bathory’s legacy, the house becomes a shifting, inescapable trap as a supernatural force awakens. A descendant of Bathory is revealed to be possessed by her spirit following a failed ritual, and the group is hunted through the living, maze-like building. As reality bends and escape becomes impossible, the survivors realize the house may be a prison designed to contain Bathory’s evil—and that stopping her may be the only way out.
