Pop superstar Alfred Moretti causes a media frenzy by announcing his first new album in 30 years. He invites six guests to a listening party at his Utah compound: journalists Stan Sullivan and Ariel Ecton, talk show host Clara Armstrong, influencer Emily Katz, paparazza Bianca Tyson, and radio shock jock Bill Lotto. Their invitations include assorted merchandise, the new album, and a book. At the compound, their electronic devices are collected by a staff of cultists dressed in denim uniforms. Moretti professes to simply be a member of the Levelists, who believe in the book given to each of the guests. Ariel is put off by the atmosphere, while the other guests are thrilled to be in Moretti's presence. Each guest is assigned a Levelist as a "concierge". Belle is Ariel's concierge, and instead of tending to her needs, she surveils Ariel constantly. As Bill unwinds with a massage, he is attacked and is not seen the next day. The Levelists insists Bill is fine and just resting. Ariel discusses ideology with Moretti. When she asks what Levelists do, he shows her a cultist shucking oysters. Moretti explains they all search for pearls to make into necklaces. During the "Fashioning" segment of the schedule, Ariel is given a makeover and forced into having her pubic hair shaved. The other guests laugh it off awkwardly, and they are taken to watch Moretti perform a song. During the show, Emily has a debilitating coughing fit and is taken away. Afterward, Ariel raises the alarm about the Levelists' controlling behavior and the disappearance of Emily and Bill. Stan is busy dismissing her concerns when he is shot in the shoulder with an arrow by a young Levelist who apologizes profusely. Ariel sneaks away from Belle and finds the guests' phones stored in a taxidermy facility. They have been rendered useless. She is too distressed to notice Bill's decapitated corpse nearby. She packs her things and asks to leave. Moretti convinces Ariel to attend a puppet show while she waits for the bus to take her home. The guests are seated in beanbag chairs and made to watch a puppet of
Billie Holiday interviewed by paparazzi rats. Ariel is startled when her chair moves. Eventually, Emily claws her way out of it. Her tongue is horrifically swollen, and Moretti finally admits to poisoning her. The Levelists attack the guests, killing Stan and Bianca. Ariel flees to a replica of Moretti's childhood home. Bill's head is mounted on a wall. She also finds
cyanide and champagne. Belle tracks Ariel down and overpowers her. Ariel regains consciousness at a ritual where the Levelists drink champagne. Clara is killed, but one of the cultists frees Ariel, who escapes. When she returns with the police, Moretti is calmly playing the piano surrounded by the corpses of his five guests. Two years later, Ariel's book about her experience is a bestseller. The Levelists' bodies have not been found, and Moretti is serving several life sentences for the murders of his guests. He summons Ariel to an interview where he reveals the Levelists are all alive and well and spread throughout society. Ariel was deliberately allowed to escape the ritual, and in fact the entire point of the massacre was to kill a bunch of people in front of Ariel so she'd write a book about it that would inadvertently proselytize Levelism. Ariel is later seen guest starring on a talk show. Just as the host asks her a question about her book, she notices that she was wearing one of the pearl necklaces, indicating her being a Levelist also. Ariel is stunned. ==Cast==
