It is the most normal thing for teachers to drag students to school when they are students, but what will happen when the students are dragged away until the school is cleared? When Han woke up, he found himself in a familiar classroom, with classmates from his own class lying beside him. The time had stopped at six o'clock in the afternoon. The rotting figure slowly walking around the corner of the stairs and the strange little boy in the guard room put Class 3 and Class 3 in danger. Several classmates disappear every day, and the nightmare gradually becomes terrifying in the continuous cycle. Looking for a glimmer of hope in crisis and despair, some people do whatever it takes to survive, while others risk their lives to protect others. Every day, escaping from this terrible school and returning to that seemingly safe villa is the only desire of all children. At the end, who can discover the secret of this class, and who can escape when the countdown ends?
