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.
Siv loves sex, while her 17-year-old daughter Birthe is frigid. Soon, however, Birthe's sexuality is awakened. The film focuses on the gap between the generations - heavily influenced by 1960s youth rebellion.
