Sonia and David, a young couple from Paris, are on their way to the house the young woman has just inherited from her grandmother in the southwest of France. As soon as she enters the place, Sonia gets very strange feelings and begins to hear terrifying noises. She also feels the presence of an increasingly disquieting person. She is so frightened she wants to leave on the spot; but David can't feel or see any of the things she describes. However, when Sonia gets kidnapped, her boyfriend begins to sense something is going on. He decides to investigate in order to get the young woman back. As he does so, he will meet disturbing characters, unexpected and undreamed-of help, and a truth from beyond.
