At dawn, the paramedics carry the body of a young woman from a villa in the Grunewald forest. Her name is Daisy, she was a successful medical student in her eighth semester. The plot jumps back a few days: Daisy has passed her pathology exam with distinction. Daisy's roommate Marie is celebrating the completion of her medical studies in the villa. A scandal breaks out during the party. Marie's boyfriend of many years, Bubi, flees from a petty bourgeois future at the side of the newly qualified assistant doctor. He leaves the party with a younger student. Despite her outward successes, she seems deeply dissatisfied, alternating between stimulants and tranquilizers and changing her sex partners more and more frequently. She now gets a particular kick out of making the abandoned Marie her lesbian lover.
