The third act takes place in the camp at Fontenoy where Cotignac announces that Parisian star Mme. Favart will perform in "La Chercheuse d'esprit" by her husband. Suzanne is anxious that if she has to go on stage it will be obvious that she is not the actress. Now Hector and Justine arrive at the camp disguised as a pair of Tyroleans ; she is amazed to see that she is billed to appear before the camp, including the King. She goes to his tent to try to explain her situation, but the monarch believes that she is just acting. Just as Pontsablé is about to wreak vengeance on Suzanne and Hector, Madame Favart pulls a note from a bouquet given by the King announcing the resignation of the Governor. Hector and Suzanne are now free to go and Favart is appointed as the manager of the Opéra-Comique.
