On a soft summer night in Vermont, twelve-year-old Lisa went into the woods behind her house and never came out again. Before she disappeared, she told her little brother, Sam, about a door that led to a magical place where she would meet the King of the Fairies and become his queen. Her little brother, Sam, has grown up to be a levelheaded man who is still convinced that Lisa was abducted by a predator. When his girlfriend, Phoebe, receives a phone call from a frightened woman claiming to be Lisa, the two are seriously spooked and set out to discover the true identity of the mystery caller and what really occurred 15 years ago.
