The first season follows the Harmon family: Ben (Dylan McDermott), Vivien (Connie Britton) and teenage daughter Violet (Taissa Farmiga), who move from Boston to Los Angeles after Vivien gives birth to a stillborn baby and Ben has an affair with Hayden (Kate Mara), one of his students. The family moves to a restored mansion, unaware that the house is haunted. The house also 'comes with' Moira O'Hara (Frances Conroy/Alexandra Breckenridge), a housekeeper who, to men, appears as young and seductive, but, to women, old and matronly. Ben and Vivien try to rekindle their relationship as Violet, suffering from depression, finds comfort with Tate Langdon (Evan Peters), one of Ben's new patients. Neighbor Constance Langdon (Jessica Lange) and "burned man" Larry Harvey (Denis O'Hare) routinely and frequently affect the Harmons' lives. The Harmons' lives are further complicated when Hayden comes to L.A. in an attempt to win his love and is subsequently murdered, and Vivien has sex with Ben and a costumed man she believes to be Ben but is actually Tate, ending up pregnant with twins, one fathered by each man. Several ghosts in the house, including Tate and Hayden, conspire to drive Vivien mad so that they can raise the babies as their own. Violet attempts suicide, something she doesn't realize was actually successful until weeks later when she discovers she cannot leave the house. Vivien gives birth to the twins in the house, but dies during labor. The first twin dies moments after birth, but the second lives. Vivien's and Violet's ghosts urge Ben to flee the house. In so doing, Ben is confronted by Hayden who murders him by forcibly hanging him. Upon finding Ben's body, Constance abducts the baby. The series then jumps ahead three years to reveal that Constance has continued to raise her grandson Michael in secrecy. She discovers, however, that he has violently murdered his nanny.
