In a bourgeois home during the early stages of the French Revolution, sisters Élodie and Marguerite engage in a heated argument over their differing political beliefs. Élodie passionately supports the revolution, advocating for equality and justice, while Marguerite staunchly defends the monarchy, prioritizing stability and order. The argument escalates as Marguerite hurls a deeply personal insult at Élodie, reminding her of their father's favoritism and past disciplinary actions. Enraged, Élodie lunges at Marguerite, who quickly hides behind you. Marguerite manipulates the situation, portraying herself as the victim of Élodie's madness, while Élodie implores you to declare their support for the revolution, believing they share her beliefs. The sisters' rivalry for you's affection intensifies amidst their political differences and personal animosity.
