Futoncritic.com's synopsis reads, "The girls of Kappa House are dying for new pledges. Kappa House, the most sought-after sorority for pledges, is ruled with an iron fist (in a pink glove) by Chanel Oberlin (Emma Roberts, "American Horror Story: Freak Show," "Scream 4"). But when anti-Kappa DEAN CATHY MUNSCH (Jamie Lee Curtis, "Halloween," "A Fish Called Wanda," "True Lies") decrees that sorority pledging must be open to all students, and not just the school's silver-spooned elite, all hell is about to break loose, as a devil-clad killer begins wreaking havoc across the campus in the all-new "Pilot/Hell Week" special two-hour series premiere episode of SCREAM QUEENS airing Tuesday, Sept. 22"

Ryan Murphy recently opened up to E! Online about how he was able to get Ariana Grande to join the cast.

"Here's the thing: When you tell somebody, 'I love you. I have always loved you work and I want to show people a different side of you,' it's sort of an interesting thing that in my case I've been very lucky where they're like 'OK.' That's what happened with Ariana. But, well, actually the truth is she was just obsessed with 'American Horror Story,' like she was obsessed, so I think she just met me to ask questions about the new season to be honest!! [laughs] I really do."
