The lovers Nina and Teodoro are in despair since Nina is promised to another man, Ernesto. Their friend Sigismondo (who is mistakenly jealous of his wife Camilla) concocts a scheme to help the lovers. Inspired by Molière's Monsieur de Pourceaugnac, Sigismondo proposes that he and his wife will dress up as on "Fat Thursday". Then they will play tricks on Ernesto, whom they believe to be a mere simpleton, so that he will flee in confusion. Sigismondo will pose as a friend from Ernesto's past, and Camilla, as a former lover betrayed by Ernesto. When Ernesto arrives, he happens to learn of the scheme, and decides to turn the tables on the others. Pretending to be deceived, he treats Sigismondo as an old friend and treats Camilla as his former lover, which confirms Sigismondo in his misplaced suspicions. Only when Nina's father the Colonel is back does Ernesto confess to everyone that he, the supposed simpleton, has outwitted them. Ernesto consents to the wedding of Nina and Teodoro, Sigismondo promises never to be jealous again, and all praise the carnival season.
