In “Chainsaw,” Chanel #5 angrily leaves Kappa Kappa Tau. She is frightened by The Red Devil’s killing spree and angry at Chanel Oberlin for being apathetic. Chanel decides to replace Chanel #5 with Hester “Neckbrace” Ulrich. Chanel gives Hester an ultimate beauty makeover and enlists her as one of her loyal minions; Chanel #6.

KKT pledges Grace Gardner and Zayday Williams and the KKT security guard Denise Hemphill go upstairs to Chanel #2’s room and find bloodstains on the floor. The trio realize that Chanel #2 must have been murdered by The Red Devil. They are confused when they find out that Chanel #2 has been posting photos to her Instagram account. Grace, Zayday, and Denise decide to get some answers from Chanel #2’s parents. They find out that Chanel #2 used to date Chad Radwell, Chanel’s promiscuous ex-boyfriend.

Denise comes to a conclusion that there has got to be more than one killer. Denise accuses Zayday of being one of The Red Devils, because of her hatred of KKT’s bad morals. Grace accuses Chad of being one of the killers because of his morbid obsession with death and his slight necrophilia.

Meanwhile, The Red Devil wields a new weapon on the campus of Wallace University; a chainsaw. Professor Wes Gardner recently taught a film analysis class on ‘The Texas Chainsaw Massacre,’ a horror movie based on true events. The Red Devil begins targeting the Dicky Dollar Scholars. Two Red Devils murder multiple Scholars.

Dean Cathy Munsch and Gigi Caldwell decide to move into the Kappa House due to the severe increase in murders on campus. The problem seems to be escalating and they are determined to figure out who the killers are. Gigi gets annoyed of the dean and decides to sleep on the first floor of the Kappa House. The Red Devil finds Gigi and tries to attack her. Wes comes to her rescue and The Red Devil runs away. The dean leaves her room after hearing Gigi’s screams and is accused of being the killer by Gigi and Wes.
