After a couple of theatre critics discover him while riding in his cab, one of them recommends him to a radio producer (Grant Mitchell).

The producer's secretary, Alice Hughes (Joan Blondell), hears him sing and falls in love with him.

When in Venice, he looks up his friend and mentor from New York City, professor de Vinci (Adolphe Menjou), who had gone ahead to use his old connections to help Dick's singing career.

Mrs. Flagenheim hears him and wants to sign him to a contract immediately, thinking he's an authentic Italian named "Ricardo Purcelli".

Dick must decide if he wants to continue masquerading as Ricardo and finally attain the fame and fortune he'd always dreamed of....or give it all up for Alice, the one he loves.

De Vinci literally runs into Dick in the street when their cabs collide and rushes him to the studio in time for the broadcast of the Flagenheim Cheese Hour with the Broadway Gondolier.
