'Scream Queens' Cheat Sheet

Wallace University's most elite sorority is run by Chanel (Emma Roberts, center) and her protégées, whose names she doesn't bother to remember so she calls them Chanel #2 (Ariana Grande), Chanel #3 (Billie Lourd, left), and Chanel #5 (Abigail Breslin, right).

Freshman Grace hopes to learn more about her deceased mother, a former Kappa, though her father discourages her from pledging. She persuades roommate Zayday to join her, along with creepy Hester (Lea Michele).

Chanel's cheating boyfriend, Chad Radwell, is part of the golfing frat Dickie Dollar Scholars, which also includes his gay BFF, Boone (Nick Jonas), and Earl Grey, who develops a romance with Zayday.

No one hates Kappa more than Dean Munsch (Jamie Lee Curtis), except for maybe someone in a Red Devil disguise. Munsch wants to destroy Kappa's snobbish policies by issuing an all-inclusive rush. But does she have an ulterior motive?

With Kappa under fire, sister-turned-lawyer Gigi comes to their defense armed with a law degree from the Caribbean and truly terrible '90s-era clothes. Also attempting to defend Kappa: security guard Denise Hemphill (Niecy Nash), who doesn't carry a gun but gives out a 1-800 number that those in danger can call.
