Pure girl Samantha Weiss (Redden Mister Leighton Meester) is a newcomer who has just entered the university campus. She and her roommates Whitney Sisens and Jenny Holden (Karin West Kailin See) volunteer to join the Dell Tapaixida (4219) sorority. There have been countless elite women in the sorority in 4219, and becoming one of them is the only way for every girl with lofty ideals. The discipline of the sorority is strict, and the sisters are even more arrogant and arrogant. In order to become a full member, Samantha studies hard and even has to break up with her high school boyfriend Oliver (Alderaan Peterf Adrian Petriw). In the process, successive members of the sorority died one after another. Samantha vaguely felt that behind the seemingly bright 4219 sorority, there seemed to be a dark secret hidden from others.
