The story takes place on the campus of Wallace University, with a fictional Kappa sorority at its core. The show begins with a flashback to 1995, when something terrible happened to the sorority, but the problem was never resolved. 20 years later, someone is looking for revenge. The audience will meet all the important characters in the first episode, and then a bloodbath begins, and these characters die one by one. Characters and actors: Emma Roberts plays Chanel, the president of the Kappa sorority, who is beautiful and fashionable, has a sense of humor, but is cold and ruthless. She has always longed to be the president, to keep the perfect boyfriend, and to rule the girls in the sorority. Jamie Lee Curtis plays Cathy Munsch, the president of Wallace University, who has just divorced. Racism on campus is a serious problem, and she is committed to eradicating it. She is a strong leader and a holy warrior, and she is willing to "kill them" in order to shut down the entire system - this is both metaphorical and literal. Keke Palmer plays Zayday, a member of the Kappa sorority, who is recognized as a genius. She doesn't like fraternities, but someone persuaded her to run for president of the fraternity, so she joined. In addition, the experience of fraternity will make her resume "colorful", which will be more advantageous for finding a job after graduation. She tried to change the existing student system, which surprised President Munsch. Abigail Breslin, Ariana Grande and Billie Lourd play Chanel's "men". They can't accept the changes in the fraternity, let alone the offensive of the president. Nick Jonas and Glen Powell play members of a golf fraternity, typical bad boys: white children from famous families, with high golf scholarships, and are the most popular boys on campus. Among them, Glen Powell's character Chad is Chanel's boyfriend. Nick Jonas's character has a "dark side". Villain: The killer in the play wears a school mascot mask-a red devil mask. The true identity of this person will not be revealed until the season finale (the mask is taken off), but you will gradually understand his motive for murder. Love story: In line with Ryan Murphy's usual practice, the show is full of polyamorous relationships, sex scenes and homosexual plots. Plot mode: The plot will develop in the mode of Harper's Island. A few characters will survive and they will appear in the next season (the next season will change the story location and villain, but retain these surviving characters and their relationships). Unlike American Horror Story, this is a series and the story is continuous.
