About the further adventures of the Newton family and their dog Beethoven.

Hill House was built 130 years ago by a textile baron for his wife and children that they would never have. Instead it was filled with stories of tragedy and ominous tales of death that left the house uninhabited...or so it seemed. A century later, Dr. David Marrow discovers the house and, intrigued by its history, he invites three of his patients to the house as part of a sleep disorder study. Theo, Luke and Nell come to the sudden realization that sleep will not be on the agenda when ghosts of the past manifest in terrifying visitations and the house seems to take a particularly strong interest in Nell as Dr. Marrow's study evolves into an examination of human fear.
