The scholar (Frank Finley Frank Finlay) marries a beautiful wife (Stephania Sandrelli Stefania Sandrelli) who is very different from his age, and the scholar is very troubled because he is worried that he will not be able to satisfy his young wife. For a long time, scholars have the habit of keeping a diary. In the diary, scholars record in detail the process of sharing love with their wife, and even get the pleasure of jealousy by having an affair with their wife and son-in-law. Soon, the scholar's diary was discovered by the wife. In shame and anger, the wife decided to avenge her husband's stupidity with practical actions. So, in a family, two people, two diaries, record the desire and darkness in human nature. However, the matter did not end here, and scholars who were more and more trapped in the whirlpool of desire began to actively match their wife and son-in-law, not only to give their wife generously to their son-in-law, but also to create all kinds of opportunities for their private meeting.
