Story

Grieving the recent loss of his wife, Robert seeks peace and solitude by taking a remote job as a caretaker for abandoned properties. But his quiet assignment is about to become a nightmare.

As a severe storm rolls in, cutting off the outside world, you are tasked with securing one final property on a desolate hill. What starts as a routine checklist of chores quickly spirals into terror. Unexplained phenomena plague the halls, and a mysterious, human-like figure seems deeply connected to the house. As you investigate the dark corners of the property, you must piece together the tragic history of the former residents to survive the night and confront the sinister presence lurking in the shadows.
