Kiroku Nanbu (Hideki Takahashi) is a Catholic, teenager attending a military-tooled middle school in 1935 Bizen, Okayama, Okayama. Living in a boardinghouse, he is infatuated with his landlady's chaste daughter, Michiko (Junko Asano). Unable to express his feelings or quell his libido with masturbation, due to peer pressure, shyness, and Catholic guilt, Nanbu turns to the only outlet left available to him: crazed, brutal violence.
