Taddeus is the manager of the Grand Hotel Excelsior. Since the Summer season started in May, many people have swarmed to the hotel: Ilde Vivaldi, in love with Taddeus; and the boxer Pericle Coccia who has an important match and falls in love with Maria. There is the Mago di Segrate, trying to win world fame by levitating 30 meters high. And there is the waiter Egisto whose daughter is in a Swiss college believing her father is a man of importance.
