Un panadero que ha hecho fortuna se lanza al comercio de pasta. Un amigo, harto de su superficialidad y de sus ínfulas de nuevo rico, decide engañarle y organiza la falsa visita de un príncipe a su empresa.
Lamenting Thebian women are waiting for the men to come back from war. God Jupiter is attracted to one of them: Alkmene. He goes to earth and tries to seduce her as himself: an old man. Failing in this, he disguises himself as Amphitryon (Alkemene's husband) and tries again. Next morning Amphitryon and his men come back from war; he suspects adultery and wants a divorce. Jupiter's wife Juno now also comes to earth and clears things up.
