Antonelli and Gasparo, courtiers of Francisco de Medicis, duke of Florence, bring to Count Lodovico in Rome the news that he is banished because of his notorious intrigues and bloody murders. Lodovico cannot understand why he is singled out for punishment when other noblemen, especially the duke of Brachiano, are guilty of crimes just as heinous.
Brachiano is trying to seduce Vittoria Corombona, wife of the aging Camillo. Helping Brachiano in his scheme is Vittoria’s unscrupulous brother Flamineo, who convinces Camillo that the best way to keep Vittoria virtuous is to give her unlimited freedom. This privilege granted, Vittoria keeps an assignation with Brachiano. Through the transparent symbolism of a dream that she fabricates, Vittoria urges her lover to murder Isabella, his wife, and Camillo, her husband. Just as Brachiano declares his love for Vittoria and his understanding of her design, Vittoria’s mother, Cornelia, discloses herself to denounce the two and to announce the arrival of Brachiano’s wife in Rome.

Disgusted by their sister’s vow but convinced that she will soon retract it, Francisco and Monticelso turn their attention to Camillo and Marcello, another of Vittoria’s brothers, whom they decide to appoint joint commissioners in charge of combating the pirates reportedly led by the banished Lodovico. Camillo objects because he fears he will be cuckolded during his absence from home, but Monticelso’s promise to keep an eye on Vittoria quiets him. Actually, Monticelso and Francisco are giving Camillo the commission to get him away from Rome so that Brachiano might have free access to Vittoria. By this scheme the two brothers hope to plunge Brachiano into a shameful scandal.
