Erminie
Erminie is promised in marriage to Ernest, but she loves her father's secretary Eugène, while Ernest loves Eugène's sister Cerise. Thieves Ravennes and Cadeaux rob Ernest and disguise themselves to attend the engagement ceremony; Ernest arrives later and is falsely accused and jailed. In a second farcical scheme, the robbers' plans fail, and Erminie and Eugène, as well as Ernest and Cerise, are united.
