The action takes places in 1558, in the court of King Henri II. Mademoiselle de Chartres, who has become the Princess of Clèves after her marriage, encounters the Duke of Nemours. Between them an instant and blinding love is born, which the princess's mother begs her daughter to give up.
Today in Marseilles, the students at Lycée Diderot use The Princess of Clèves to talk about their own lives. When we're 17 years old, we love intensely, we conceal and confess our love. It is the age of first choices and first renunciations.
