The beginning of the 20th century. The main character is the young, charming Count Pierre de Sauterne. There have been several conflicts between him and his aristocratic uncle, who, due to his fanatical interest in cars, is called Tøf-Tøf. The authoritative older gentleman also has a pronounced weakness for the female sex, and it irritates him that his nephew far surpasses him in this regard. Uncle Tøf-Tøf decides that Pierre must spend his summer vacation in a secluded family villa on the North Sea coast as punishment, but not long into his stay, two charming girls seek shelter from a thunderstorm.

When a high-school girl complains of her inability to reach sexual climax, her doctor suggests that she keep a diary of her sexual encounters. She does just that and soon finds herself caught up in a sexual merry-go-round that includes making a hardcore porno film in Sweden, an escapade with a German sadist and a lesbian encounter.
