L’occasione fa il ladro
During a storm, Alberto and Don Parmenione take shelter at an inn. Alberto is travelling to meet his betrothed, while Parmenione is searching for a friend’s missing sister. After the storm, they accidentally exchange luggage. Finding a portrait among Alberto’s papers, Parmenione decides to pose as Alberto and claim the bride. At Don Eusebio’s house, Berenice also disguises herself as a maid so she can judge her intended husband, while her friend Ernestina pretends to be Berenice. Parmenione courts Ernestina, and the real Alberto falls for Berenice. When both men claim to be Alberto, Berenice’s questioning exposes Parmenione’s deception. Berenice marries Alberto, and Parmenione marries Ernestina, who proves to be the friend’s sister he had sought.
