Lesbina, housemaid of Tritemio, in order to avoid that Nardo meets Eugenia, takes the place of the girl.

After a series of misunderstandings, Nardo learns of the true identity of Lesbina, but he accepts the housemaid all the same and remains in love with her.

When the notary arrives, without Tritemio knowing it, a double wedding is celebrated, between Nardo and Lesbina and between Rinaldo and Eugenia.
