The lifestyle of Vicomte Florestan, a dashing but feckless young aristocrat, has left him in severe debt. His uncle, tired off paying off Florestan's debts, has made him promise to get married or go to prison as a bankrupt. Florestan has chosen the arranged marriage; he will be presented to Hélène de Solanges, the rich heiress chosen as his fiancée, that evening at a court ball. Florestan has been having an affair with Agathe Coquenard, the wife of the owner of the florist shop where the action takes place. Old Monsieur Coquenard, who flirts with the flower shop girls, is hoping that, despite his incompetence with a sword, his nomination to be a captain in the Garde Nationale will arrive soon.
