For over a century, the dark and forbidding Hill House has sat alone and abandoned… or so it seemed. Intrigued by the mansion storied past, Dr. Marrow lures his three subjects - Theo, Nell and Luke - to the site for a seemingly harmless experiment. But, from the moment of their arrival, Nell seems mysteriously drawn to the house... and the attraction is frighteningly mutual. When night descends, the study goes horrifying awry as the subjects discover the haunting secrets that live within the walls of Hill House.
