Describing herself as a "trouble magnet," Zeynep finds herself in the middle of chaos on her first day at her new school. An outbreak forces the school into lockdown, and that night, she stumbles upon the lifeless body of a female student in the dark hallways. She’s not alone—she’s joined by Onur Zorlu, the school principal’s son, and his friends Burak and Mert. Fearing his father’s weak heart won’t handle the news of a murder, Onur proposes they keep it a secret until the quarantine is lifted and find the killer themselves. With a disease outbreak and a murderer on the loose, the group believes their only option is to solve the mystery without alarming the parents outside. Drawn into this dangerous plan, Zeynep becomes the fourth, unexpected member of their group. Together, they embark on a perilous journey full of secrets, danger, and twists they never saw coming.
