"You may not believe in ghosts but you cannot deny terror."
Dr. John Markway invites three distinct individuals to the eerie and isolated Hill House to be subjects for a sleep disorder study. The unfortunate guests discover that Markway is far more interested in the sinister mansion itself — and they soon see the true nature of its horror.
