Yuko Moriguchi is a teacher who spends her days looking after a class of frequently unruly seventh graders. One day, Yuko calmly announces to her class that she's leaving her job soon as she's still struggling with the recent death of her young daughter. She adds that she knows who was responsible for the child's drowning, they happen to be among the students in her class -- and that the milk they're drinking may just be infected with a deadly disease. Though a series of flashbacks, we become witnesses to Yuko's difficulties with her students, the actions of the nameless students she believes are guilty of murder -- one of whom is planning vengeance against Yuko, while the other sinks deep into paranoia -- and the incidents that suggest the likely innocence and guilt of the parties involved.
