Les Enfants terribles
After their mother’s death, siblings Paul and Elisabeth live in an isolated, shared fantasy world. Elisabeth marries Michael, who dies the next day, leaving her a fortune. Paul’s friend Gérard and Gérard’s friend Agathe, who resembles Paul’s idol Dargelos, join them. Elisabeth manipulates events to prevent Paul and Agathe from forming a life together. Dargelos later sends Paul a poisoned ball; Elisabeth kills herself and Paul, preserving their adolescence in death.
