The highly respected congressman (Vitttorio Caprioli Vittorio Caprioli) has a failed son Franco (Alfredo Bayer Alfredo Pea). Franco does not want to learn how to improve himself all day long, and his head is full of bad thoughts about spring, which makes the congressman feel very distressed. The principal of Franco's school found the congressman, hoping that he could hire a tutor for Franco to improve his grades, so the congressman brought in the gentle and beautiful tutor Gibbana (Edvich Finnizi Edwige Fenech), hoping that her amorous feelings would make Franco fall in love with learning. However, the distance between reality and ideal is always far away, in front of Gibbana, Franco can not concentrate at all, only thinking about how to get this beautiful thing, but in desperation, Gibbana decided to do what he likes and set up a "physiology class" for Franco.
