Set in the titular year, 1984, the season follows Brooke Thompson (Emma Roberts) as she travels to a remote, newly reopened summer camp, known as Camp Redwood, to work as a counselor following a terrifying encounter with serial killer Richard Ramirez (Zach Villa). 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). Upon arriving at the camp, they encounter its owner, the deeply religious Margaret Booth (Leslie Grossman), who was once a camper there, and who has her own experience surviving a killer.
