Cast & Crew
Miho Sakai, a high school day student, wonders who occupies her desk during night classes and decides to leave a letter of encouragement for the student. Kenta Namiki, a night student who works during the day as a mechanic, finds the note, which sparks his resentment over the condescending attitude he feels the day students take toward the working class night students. He leaves Miho an obscene note, enclosing some of his pubic hair. In retaliation, two day students, Hiroto Miyagawa and Yuji Shibata, raid the night students, barely escaping with the help of Taeko, a girl night student. Taeko seduces Hiroto, who is shocked at first but then becomes completely enslaved to sex. In revenge, Shibata rapes Yuki Nohara, Kenta's girl friend and the brightest of all the night students. Regretting his rash action, Shibata wants to marry Yuki, but he is scorned by Kenta when he asks for the night student's help. Eventually, the two boys become friends, helping to effect a reconciliation between the two student groups by staging a motorcycle race.
