When Sarah inherits a crumbling motel on the edge of the Mojave Desert, she discovers that Room 9 has been locked for fifteen years. The previous owner left one instruction: never open it. But Sarah needs the revenue. She needs answers. And the guests have started complaining about the sounds coming from inside—scratching on the walls, whispers through the vents, and a voice that calls their names at 3:47 AM every night. Some doors are locked for a reason. Sarah is about to find out why.
