On last night's Scream Queens, Chanel Oberlin (Emma Roberts) plans the biggest Halloween party ever, complete with a pumpkin patch, maze, and performances by Maroon 5 and Fergie. But when Dean Munsch (Jamie Lee Curtis) decides to enforce an early curfew for all students because of the serial killer on the loose, Chanel's Halloween plans are thwarted and she gets angry. She's not the only upset one though—the rest of the Kappa Kappa Tau's and Dickie Dollar Scholars protest the curfew as well, with Chad (Glen Powell) claiming Halloween to be "the best night of the year."
Chanel secretly sends out invitations to her party regardless, finding a loophole in the dean's curfew rules. She insists that all the Chanels dress as the wives of dead presidents as their Halloween costume, with her being Jackie Kennedy. Chanel No. 5 (Abigail Breslin) throws a fit when she finds out she has to be Mary Todd Lincoln and her resentment towards Oberlin grows.
Soon after, Chanel is arrested for the murder of Miss Bean. Coincidence? She is convinced that No. 5 ratted her out to the dean for killing the housekeeper. With the KKT presidential election around the corner, tension is at an all-time high in the house and Chanel thinks that No. 5 wants to replace her. Chanel No. 3 (Billie Lourd) eventually bails Oberlin out of jail with her dad's money. When she returns to the house to confront No. 5 about her backstabbing, the minion is wearing Chanel's Jackie Kennedy costume in preparation for the pumpkin patch party. Oberlin loses it and forces No. 5 to light all the pumpkin candles outside by herself, past curfew. With the red devil on the prowl, this is a dangerous and cruel ask. Chanel No. 5 does as she's told but brings two Dickie Dollar Scholar members with her as protection. But when the three get chased into the giant party maze by the red latex-wearing serial killer, one of the frat bros is stabbed and dies.
Meanwhile, Zayday (Keke Palmer) is still missing, so Grace recruits a search party to help find her friend, including Pete (Diego Boneta), her dad (Oliver Hudson), Gigi (Nasim Pedrad), and security guard Denise (Niecy Nash). They use the Find My Phone app to locate her whereabouts and track her to a basement of an old house. Once inside, they realize it's the killer's secret lair, filled with murdery tools and lots of red devil paraphernalia. They even find a prisoner hole, but no sign of Zayday.
Back at the Kappa house, Chanel is even more upset because her pumpkin patch party officially had to be canceled on account of the Dickie Dollar Scholar who was murdered in the maze. She calls an impromptu election instead, but just before the votes are cast, Zayday walks in and throws her name in the running. But before they vote, the pledges make Zayday tell them how she escaped the red devil. According to her, he's in love with her and tried to woo her with roses and Oakland nachos in his creepy evil lair. She escapes after stabbing him in the hand with a fork and runs straight to the sorority house.
In a twist at the end of the episode, Gigi meets with ... the red devil serial killer? We'll have to tune in next week to find out what happens!
