It's late at night. It is raining. You are a traveler, tired after a long journey. The only shelter you have is an old motel on the highway. It looks ordinary: dim lights, a shabby reception desk, a polite but strange concierge. He keeps repeating one thing: don't go near the wall. He says something is wrong in Room 8. You stay the night and start looking for answers. What happened in this motel? Why is no one going into Room 8? And is it true that someone is still watching from inside?
