 Sincere but struggling sculptor Tommasso (Caruso--bushy moustache, gawky) works in an ornamental plaster shop, but his masterpiece on the side is a bust of his cousin Caroli (Caruso--no moustache, polished), who is the Metropolitan Opera s leading tenor. Tommasso hopes to marry his model Rosa, but her father, restaurant owner Pietro, wants her to find someone more settled and money-conscious, such as the greengrocer Lombardi down the street. Tommasso, he says, throws away his money, such as for a pair of tickets to take Rosa to the opera to see his famed cousin. After the opera, the cousins cross paths in the swanky Galeotto s restaurant, but when neither recognizes the other, Tommasso is generally mocked and Rosa believes him a liar and unworthy. Tommasso must recover his reputation and make a sale, preferably the Caroli bust to his cousin, in order to win Rosa back.
