They move into a restored mansion and soon encounter the residence's housekeeper, Moira O'Hara (Frances Conroy and Alexandra Breckenridge), as well as their neighbors—the eccentric Langdon family, consisting of Constance (Jessica Lange) and her daughter Adelaide (Jamie Brewer), who has Down syndrome.

The Harmons' lives are troubled by the meddling Langdons, the incompetent realtor Marcy (Christine Estabrook), as well as the disfigured Larry Harvey (Denis O'Hare), a former resident of the mansion who is secretly in love with Constance, and the scorned Hayden McClaine (Kate Mara), Ben's former student who follows him to Los Angeles.

The family soon discovers that the home is haunted by the ghosts of anyone who has ever died on the property, including its creators Charles (Matt Ross) and Nora Montgomery (Lily Rabe); and their deformed son Thaddeus (Ben Woolf) who is sometimes referred to as the 'Infantata'.

At Briarcliff, Kit meets the other patients, many of whom claim to be unjustly institutionalized, including microcephalic Pepper (Naomi Grossman), nymphomaniac Shelley (Chloë Sevigny), whose cheating husband hypocritically committed her after finding her in bed with two guys; and the unassuming Grace Bertrand (Lizzie Brocheré) from France.

Believed to be a violent serial killer, Kit becomes the subject of interest of pragmatic psychiatrist Dr. Oliver Thredson (Zachary Quinto) and the sadistic Dr. Arthur Arden (James Cromwell), the latter of whom routinely conducts scientific operations on patients.

The school is run by headmistress Cordelia Foxx (Sarah Paulson), head of the Witches Council and eccentric fashionista Myrtle Snow (Frances Conroy), and the mute butler Spalding (Denis O'Hare).

Other members of her troupe include "Lobster Boy" Jimmy Darling (Evan Peters), who dreams of living a normal life, and his mother Ethel (Kathy Bates), a bearded lady who acts as Elsa's second-in-command by maintaining law and order under the tent.

Set in 2015, the season follows the strange and dangerous happenings that seem to center around the retro Hotel Cortez in downtown Los Angeles, California, initially built as a secret torture chamber to fulfill the violent desires of founder James Patrick March (Evan Peters).

Throughout his investigation, John also becomes entangled with the spirits of a heroin junkie named Sally McKenna (Sarah Paulson), hotel maid Hazel Evers (Mare Winningham), and James Patrick March, who is looking for a protégé to continue the violent acts he started when he was alive.

The hotel's tireless staff includes the surly front desk manager Iris (Kathy Bates), Donovan's mother, and her best friend, the transgender bartender Liz Taylor (Denis O'Hare), both of whom hesitantly cater to Elizabeth and her vampiric children, one out of a desire to remain close to her son and the other out of a sense of loyalty.

Elizabeth's relationship with Donovan becomes troubled with the arrival of attractive male model and cocaine addict Tristan Duffy (also played by Wittrock), New York fashion designer Will Drake (Cheyenne Jackson), and her scorned ex-lover Ramona Royale (Angela Bassett), all of whom become entangled in her violent life.

The documentary becomes a huge success, featuring dramatic reenactments of the Millers' story starring Audrey Tindall (Sarah Paulson) as Shelby, Dominic Banks (Cuba Gooding Jr.) as Matt, Monet Tumusiime (Angela Bassett) as Lee, Agnes Mary Winstead (Kathy Bates) as Thomasin White—also known as The Butcher, leader of the ghost colony, Audrey's husband Rory Monahan (Evan Peters) as Edward Philipe Mott, the creator and first owner of the house, William van Henderson (Denis O'Hare) as Dr. Elias Cunningham, a professor who becomes entranced with the paranormal happenings of the area, and Dylan Conrad (Wes Bentley) as Ambrose White, Thomasin's son, and accomplice.

Across town, misogynistic alt-righter Kai Anderson (Evan Peters) rejoices at the election results, enticing him to pursue political power by running for city council, led by radical feminist Bebe Babbitt (Frances Conroy) and with the help of his reluctant, liberal sister Winter (Billie Lourd), who the Mayfair-Richards household hire as their nanny.

Also in the midst of the chaos is Jack Samuels (Colton Haynes), a detective who investigates the crimes and is initially doubtful about Ally's claims, and Gary K. Longstreet (Chaz Bono), a supermarket owner who has an amputated arm and is a passionate Trump supporter.

The chosen survivors of the aftermath, heiress Coco St. Pierre Vanderbilt (Leslie Grossman), her personal assistant Mallory (Billie Lourd), hairstylist Mr. Gallant (Evan Peters), his grandmother Evie (Joan Collins), talk-show host Dinah Stevens (Adina Porter), Stevens' son Andre (Jeffrey Bowyer-Chapman), young adults Timothy Campbell (Kyle Allen) and Emily (Ash Santos), among others, take refuge in a fallout shelter named "Outpost 3", run with an iron fist by Wilhemina Venable (Sarah Paulson) and Miriam Mead (Kathy Bates) along with The Fist (Erika Ervin), a brutish and tall female guard.

Flashbacks to three years prior reveal that "Outpost 3" was an all-boys warlock school led by John Henry Moore (Cheyenne Jackson) that unknowingly harbored the Antichrist, in hopes that he would rise as the first ever male Supreme.

Those traveling with Brooke include preppy Xavier Plympton (Cody Fern), athletic Chet Clancy (Gus Kenworthy), easy-going Ray Powell (DeRon Horton), and spunky Montana Duke (Billie Lourd).

Not long after the counselors settle into their first week, news breaks that deranged murderer Benjamin Richter (John Carroll Lynch), also known as Mr. Jingles, has escaped a local insane asylum and is presumed to be heading for the camp, where he has a violent history.

Harry suffers from writer's block and later goes to a bar called the Muse one night, where he meets singer and songwriter Austin Sommers (Evan Peters) and erotic novelist Sarah Cunningham, known by the pseudonym Belle Noir (Frances Conroy), who assist him with his problem.

In Part 2, titled Death Valley, Kendall Carr (Kaia Gerber), Cal Cambon (Nico Greetham), Troy Lord (Isaac Cole Powell) and Jamie Howard (Rachel Hilson), four college students who are on a camping trip are swept up in a horrifying and deadly extraterrestrial conspiracy that has been developing for decades.

Meanwhile, Dr. Hannah Wells (Billie Lourd) investigates a new disease spreading from Fire Island while Cabaret singer Kathy Pizzaz (Patti LuPone) handles decreasing audiences at her local bathhouse venue.

Despite concerns from her friend and PR manager, Siobhan Corbyn (Kim Kardashian), about the impact on her career during an already intense award season, Anna is determined to become a mother through IVF treatment with the prestigious Dr. Andrew Hill (Denis O'Hare).

Later that month, Cody Fern, Leslie Grossman, Billie Lourd were confirmed to return to the series, with John Carroll Lynch being promoted to the main cast after his third appearance in Cult, also with newcomers Zach Villa and Matthew Morrison.

[127] Ken Tucker from Entertainment Weekly awarded the pilot episode a B+, stating: "AHS is pretty much all scare, all the time: a whole lotta screams, sex, jolts, mashed faces, psychotic behavior, and dead babies.

"[158][159] On the other hand, Matt Zoller Seitz of New York Magazine found the season "confusing, tedious, annoyingly precious, and often ostentatiously brutal", but also praised it for being "darkly beautiful, deeply weird, and (sometimes) exhilarating.
