Paris, 1887. Duels have been officially outlawed but are still regular practice. For many, they are the only way to defend their honor. Fencing master Clément Lacaze tries in vain to prevent his nephew from engaging in an uneven duel with the more experienced Colonel Berchère. Marie-Rose Astié de Valsayre, a feminist fighting for women’s equality, tries to show that honor is not just a male affair. Actor and director Vincent Perez’s historical film makes excellent use of various forms of duels  – with épées, pistols, and sabres on horseback.
