Catherine Deneuve's first appearance is a beautiful and experienced teenager who is placed in a French girls boarding school because her father apparently committed suicide due to a business scandal. She immediately gained admirers - a lecherous middle-aged artist, a handsome young composer, a female classmate - and a jealous opponent. With the help of her classmates, she attempted to elope with the composer, but the adults caught the plot and she was locked in her room at night.
