Isabella continues to refuse to apologize to Prince Carlo for scolding him, so he leaves her in the dungeon and goes off to a ballroom dance in Naples. Unbenownst to Prince Carlo, Isabella escapes the dungion, disguises herself and meets him at the ball where they dance and flirt. When Prince Carlo returns from the ballroom in Naples to the dungeon to see if Isabella will apologize, she again refuses. So Prince Carlo decides to attend a garden party in Apulia. Again, Isabella escapes the dungeon and disguises herself and dances with Prince Carlo, who is of course bewitched and begiuled by her charms. Upon his return from the garden party in Apulia, he returns to the dungeon, where again Isabella refuses to apologize. Finally, Prince Carlo goes to Vienna and waltzes with Isabella, who naturally is disguised. This time, when he returns to the dungeon he declares he's fed up with Isabella's lack of apologizing and he is going to marry a princess from England instead. At the wedding, Isabella appears with all of her disguises and admits that in fact, it was her he had been dancing with all those times. They both realize they are in love and decide to get married again and live happily ever after (let's hope!).
