In order to help the photography and film club, which is on the verge of being disbanded, a beautiful and Kokoro student teacher decides to star as the heroine in a film planned by the club members for the school festival. She endures the embarrassing costume prepared for her and tries her best to perform her poor acting, but she is mercilessly criticized and, in what may be acting instruction, is tied up in obscene poses as the filming progresses. As the filming becomes more and more heated and radical, the girl gradually becomes suspicious, and the club members tell her that they have actually changed course and are filming adult videos instead of movies. But it is too late, and her youthful sexual desire explodes!
