Weary from endless days on Arizona's backroads, traveling inspector Jason Schulz just wants a quiet night's sleep when a blown tire strands him at the historic Jerome Grand Hotel. But Room 436 offers no rest. Awakening at 4:36 AM, Jason is thrust into terrifying visions of the building's past as a 1930s hospital, and discovers an ancient entity lurking beneath the mountain's copper veins. Fueled by decades of suffering, the Harvester doesn't just haunt the hotel; it feeds on human consciousness. As a mysterious locket binds him to a dead man's memory, Jason realizes he may never truly leave Jerome.
