Things change, however, when she sees the ghostly figure of a small, sad boy who mysteriously disappears before she can talk to him. Convinced that he's a ghost, Christina sets out to discover why he's there. Could he be linked to the murders that happened in the house thirty years before? And what evil, chilling presence is lurking in the attic?
