Therese (Essy Persson) is sent to an all-girl school when her mother marries a man who dislikes children. She meets Isabelle (Anna Gael) and the two become fast friends. After they experience unfulfilling and often brutal sexual encounters with men, the two turn to each other and become lesbian lovers.
Plenty of nudity and sexual situations ensue, and the women find love in each other's arms. When Isabelle's parents remove her from the school, the lonely Therese returns home to her fiancé. The story is told in flashback form as Therese visits her old school after 20 years.
