In 1887, at a time when duels are in vogue in Paris, Clément Lacaze and Marie-Rose Astié meet. He's a charismatic master of arms; she's a feminist, far ahead of her time. Clément gets caught in a spiral of violence and decides to initiate Marie-Rose in the art of dueling. The two must work together to save face. How far will they go to defend their honor?
