In the late 1990s, the Crain family moves into Hill House, an old mansion in Massachusetts, to renovate it and sell it. The family consists of parents Hugh and Olivia Crain and their five children: Steven, Shirley, Theo, Luke, and Nell. As they begin their renovations, strange occurrences start to happen. Olivia begins to experience unsettling visions and becomes increasingly drawn to the house, while the children encounter supernatural phenomena. One night, after a series of disturbing events, Olivia becomes overwhelmed and loses her grip on reality.

One evening, Olivia, feeling isolated and tormented by the house, has a breakdown. She believes she is being guided by the spirits of the house and becomes fixated on the idea of keeping her family together at all costs. In a tragic turn, she attempts to take her children away from Hugh, believing that the house is trying to harm them. This culminates in a horrifying scene where she tries to suffocate Luke, believing she is saving him from the house. Hugh intervenes, and in the chaos, Olivia dies, leaving the family shattered.
