Years after literally driving a knife into the back of her female teacher, a grown-up student herself becomes the target of abuse upon accepting a position as a teacher in director Hiromasa Hirosue's school-based drama. Ryo (Akie Namiki) was once a deeply disturbed student who resorted to violence as a means to solve her many problems. After assaulting her teacher and weathering ten years of intense therapy, Ryo is now prepared to enter into the workforce by serving in the same capacity that she once so despised. As the cruelty of her middle-school students and the overwhelming helplessness felt by the colleagues gradually builds to an emotional crescendo, Ryo begins to understand the plight of the educator she once assaulted as the vicious young students gradually begin to target her too for their merciless brand of ridicule and abuse.
