Conclusion. Before Halloween night is over, Tate comes face-to-face with his past (and Violet gets a glimpse of it), and Ben and Vivien are haunted by a new houseguest. Vivien also has an unpleasant encounter with Chad (Zachary Quinto). And Ben has it out with Larry Harvey in front of the gazebo.
Part 1 of 2. It's Halloween, and the line between the living and the dead blurs at the mansion, where two previous residents (Zachary Quinto and Teddy Sears) offer the Harmons advice. One suggestion: get rid of the gazebo in the back. Meanwhile, Tate fills Violet in on some of the house's history; and Addy decides that she wants to go to the Harmons' Halloween party as "a pretty girl."
Vivien and Violet get caught in a dangerous situation strangely similar to one from the house's past. Meanwhile, Ben returns to Boston to put an end to a dark chapter in his life. But first, he sees a patient who has nightmares about being cut in half. He also refuses to treat Tate anymore because of the teen's feelings for Violet.
Bostonians Ben and Vivien Harmon (Dylan McDermott, Connie Britton) and their teen daughter, Violet (Taissa Farmiga), move into a haunted LA. mansion in the series premiere of a violent, erotically charged horror story about a troubled family. Ben and Vivien are seeking a fresh start following a miscarriage and marital infidelity, and they got the 1920s Victorian-style house for a song. But the previous occupants died in a murder-suicide, and that's only sign No. 1 that something's amiss.
