You let them back in. You shouldn't have... Young couple Charlie and Eve can't believe the killer deal they got on an old house deep in the mountains. One day, a man knocks on the door. He says he lived there years before and asks if he can show his family around. As soon as they enter, strange things start to happen, and Eve is desperate for them to leave and never come back. But they can't - or won't - take the hint that they are no longer welcome. Then, Charlie vanishes, and Eve begins to lose her grip on reality. She's convinced there's something terribly wrong with the house and its past inhabitants . . . or is it all in her head? The Turn of the Key meets Parasite in this gripping, eerily haunting debut and Reddit hit - soon to be a Netflix original movie starring Blake Lively - that will keep you up into the early hours. Perfect for fans of Stephen King and Leave the World Behind.
