Beautiful gold-digger Sonia mistakes Antonio, a waiter in a Neapolitan hotel, for Arab Prince Bey of Agapur and makes an appointment with him for the following day in Capri, and Antonio goes there behind the backs of his wife and mother-in-law. A lucky series of circumstances actually does transform him into the prince of the island.
