A room with 14 students, 12 boys and 2 girls,a bully and trouble maker. Suddenly, a new transfere came so they wanted to make fan with her. Yes its a girl. They think they can make fan with her but the time comes that the girl is really pissed off. The girls attitude is one of their too. A trouble maker too in short a bitch!! She really thinks that this school is just an ordinary one. But it wasnt, this school has a hidden hellish event. Killing is allowed during that event. Does she know that all of her classmates aren't jerks but a mafias?? What will really happen to her once her trauma came back? Will she became a killer too?
