Eleanor "Nell" Vance, an
insomniac, has cared for her disabled mother for 11 years, sharing a
Boston apartment with her. After her mother dies, Nell's sister Jane and her husband Lou inherit the residence and eject Nell to prepare for a sale. As she faces
homelessness, Nell accepts an invitation to participate in an insomnia study by Dr. David Marrow at Hill House, a secluded, sprawling
manor in the
Berkshires of
western Massachusetts. At the house, she meets Mr. and Mrs. Dudley, the eccentric caretakers. Two other participants soon arrive: the goofy Luke Sanderson, and Theodora ("Theo"), a glamorous, openly
bisexual artist. Dr. Marrow and his two research assistants, Mary and Todd, follow. Unknown to the participants, Dr. Marrow's true purpose is to study the psychological response to fear, intending to expose his subjects to terror. During their first night, Dr. Marrow relates the story of Hill House: Its original owner,
Hugh Crain, a 19th-century textile tycoon, constructed the rambling home for his wife Renee, hoping to populate it with a large family. Unfortunately, all of Crain's children were
stillborns, and Renee, devastated by the multiple losses,
killed herself, while Crain became a recluse. Mary is wounded in a freak accident involving a snapped piano wire, and leaves with Todd to go to the hospital. Supernatural events begin happening, and Nell sees
apparitions of children. A large portrait of Hugh Crain is vandalized with the words "Welcome Home Eleanor" written in blood. Theo and Luke accuse Nell, claiming she is seeking attention. Nell becomes determined to prove that the house is
haunted. She finds Crain's hidden study and learns that he extensively used
child labor in his
cotton mills. He tortured and killed orphans in his home, then burned their bodies in the fireplace. She surmises that these children's spirits are trapped in the house, providing Crain with an "eternal family". Crain had a second wife named Carolyn, from whom Nell is descended. Dr. Marrow is skeptical and reveals the truth of his fear study to the group, but after a statue comes to life and tries to drown him, he realizes Hill House is haunted. Nell reveals that she is related to Carolyn Crain and must help the children move on to the
afterlife. The group tries to leave Hill House but Hugh Crain's ghost traps them inside. Luke defaces a portrait of Crain, enraging his spirit to
decapitate Luke with a large chimney
flue. When Crain manifests, Nell realizes that he thrived on the fear he created in children and declares that she is not afraid of him. Her declaration weakens the ghost and he is cast into a decorative bronze door depicting the distressed children in
purgatory. He drags Nell with him, but the benevolent spirits release her and she dies. Nell's soul, along with those of the freed children, ascends to
heaven. The following morning, Dr. Marrow and Theo meet the Dudleys at the front gate in silence and leave Hill House behind. ==Cast==
