Return to Murder House

Madison Montgomery and Behold Chablis purchase the Murder House in Los Angeles, which has been abandoned for several years. Arriving at the house, the two perform a spell which will allow them to see the ghosts, who can otherwise hide themselves from the living.

In the living room, the ghosts of Tate Langdon and Dr. Ben Harmon are talking about Tate's frustration at being ignored by Ben's daughter, Violet. They are interrupted by Madison and Behold, who announce that they have come to learn about Michael Langdon's origins, but both refuse to speak. Madison is then attacked by the deformed boy, Beauregard Langdon, but medium Billie Dean Howard arrives and subdues Beauregard. Constance Langdon, Tate and Beauregard's mother, appears and states that she is the true owner of the house.

Behold and Madison express their desire to talk about Michael. Constance says that she will talk only if they rid her rival Moira's spirit from the house. They unearth Moira's remains from the backyard and buries them with Moira's mother. Her spirit is released from her earthly hold and greeted by the spirit of her mother. The two pass peacefully into the afterlife.

Constance tells the story of Michael Langdon to Madison and Behold, revealing that his father is her son Tate. After Vivien Harmon gave birth, Constance took Michael from the house and raised him as her own son, believing she had been given a new chance at being a mother. However, Michael quickly becomes violent, first killing small animals and eventually murdering his nanny at the age of three. Soon after, Michael aged ten years overnight and appeared as a teenager. Michael attacked Constance, then murdered a priest from whom she sought help. With her dreams of motherhood shattered, Constance returned to the Murder House and committed suicide by overdose.

Behold and Madison approach Ben, who is estranged from Vivien. He tells the two that a father-son relationship developed between the two, much to Vivien's disappointment. However, Michael learned that Tate is his father and grew darker after being rejected by him. Ben witnessed Michael mutilating the ghost of Elizabeth Short, as well as murdering and permanently expelling the spirits of two new residents from existence. Afterwards, Ben ended their sessions. At this point, Vivien appears and reconciles with Ben.

Vivien tells the story of a group of Satanists who arrived at the house, consisting of Miriam Mead, Samantha Crowe and Church of Satan founder, Anton LaVey. The Satanists kidnapped a young woman and brought her to the house to perform a Black Mass. Vivien failed in her attempt to murder Michael, and narrowly escapes the destruction of her own spirit through the intervention of Tate. Vivien tells Behold and Madison that Michael Langdon is not a warlock but the Antichrist.

Before leaving, Madison meets Violet. Violet tells Madison that Tate is a monster, but Madison believes that Tate was a vessel used by the house to conceive Michael and tells Violet that Tate is not the true evil. Madison uses her magic to prove it to Violet, leading to their reconciliation. Madison locks the gates as her and Behold depart the house.
