MORISAWA KANA plays a beautiful, serious teacher who is popular with her students but resents the lustful stares of the men around school. On the eve of a three-day holiday, she stops at the library before leaving, unaware that a man is creeping up behind her. Bound and humiliated inside the deserted school, she writhes between shame and pleasure until the sensations conquer her and she fully submits to her twisted masochistic desires.
