Hill House is a haunted structure that has been standing for decades, plagued by death and darkness. We meet Dr. John Montague, a paranormal investigator who is determined to prove, with science, that the supernatural is real. In his efforts to confirm his suspicions, he rents out Hill House for a Summer. He hopes, by the season's end, to have answers. And he invites a few others, individuals who have had paranormal experiences themselves, to join him in his quest. At first, he keeps the nature of their stay a secret.
