[3][4] Arriving in Venice for a production of "Aida", young tenor Ricardo Gatti meets the attractive Mary, who has sneaked into the opera house in an attempt to get her fiancé hired as a pianist.

Ricardo invites Mary to tea and she tells her story, describing her fiancé as her "brother".

However, filled with guilt at her deception, Mary breaks off her engagement and consents instead to marry her parents' choice, a wealthy society man.

The New York Times wrote, "the film is at its best, of course, while its star is attuning his magnificent tenor to a variety of classic arias.

The musical high spots of the show are the "Ave Maria" of Gounod, which M. Kiepura sings impressively during a church wedding, and the "Celeste Aïda," which he rehearses during an amusing backstage sequence at the opera house while "Aïda" is being trundled through its paces";[5] and TV Guide called the film "charming in parts, this is a nicely done musical with some good detailed direction.
