A young couple has rented an old, remote house by the Mediterranean sea for the summer. There they meet Elias Urquijo, an enigmatic children books writer, whom they quickly befriend. However, something in the house seems to react to the presence of the guests, something that is trying to warn them about the true identity of Elias and what are his real intentions.
