14 participants join a secret reality TV show where they must stay in a mansion for 100 days. Things start to get strange when someone throws a rock with a piece of paper with an instruction to tell scary tales at 8 in the evening. What's more is that the owner of the house, as the letter states, says that one of the participants is a killer. A harsh storm comes and the house automatically locks the participants inside. Things grow sinister when one by one the participants vanish without a trace. Was it just a part of the show where participants get evicted or something wrong is going on with the housemates?
