Every mirror inside the Hollowmere Hotel shows a different possible future. When Daniel Cross checks in for one night, he finds himself standing before a mirror that shows Mara Whitlock killing Ethan Blackwell. He doesn't know yet if the glass is warning him, tempting him, or lying to him - but by morning, someone in the hotel will be dead, and every reflection in the building will start showing him a different way it could have happened.
