One day, an old friend approaches with a job offer. She would be a substitute teacher in a class on which several teachers gave up without an apparent reason. She reluctantly takes the job only to discover that there are several brutal bullying cases inside the class. Even she eventually starts being anonymously threatened due to her opposing posture against such cases. She now has to identify and reprimand them while at the same time protecting weaker students.
