Julie, accompanied by her elderly mother, comes to take a few days off in a hotel lost in the English countryside. The young woman, director in full doubt, hopes to find inspiration there; her mother sees it as an opportunity to bring back distant memories, between the walls of this building she frequented in her youth. Very quickly, Julie is seized by the strange atmosphere of the place: the corridors are deserted, the switchboard operator has a hostile behavior, and her dog keeps escaping. At nightfall, circumstances push Julie to explore the estate. She is then won over by the tenacious impression that an unspeakable secret haunts these walls.
