Sally and her husband Alex move to a Victorian estate, far from the hustle and bustle of city life. In their new home, Sally discovers a locked door and, after finally finding the key, opens it. Behind the door is a room that used to be her father’s study. Soon after, frightening things begin to happen in the estate, and Sally notices strange little creatures everywhere. She tells her constantly busy husband about this, but neither he nor anyone else believes in their existence. Alex thinks his wife is having nervous breakdowns again, and her friends think she is simply suffering from melancholy and loneliness. Is Sally really going crazy, or has she unleashed the demons from her father’s study?
