World-famous soprano Jenny Lind and her party arrive at a Swedish inn. Jenny wants a room with a piano, but the only one suitable has already been taken by Paul Brandt, a young composer. Jenny’s companion, Pauline, demands that Paul surrender the room to the world’s greatest singer, but he pretends he has never heard of Jenny Lind. Jenny finds her friend’s behaviour embarrassing. Paul and Jenny meet and, after being arrogant and flirtatious, Paul agrees to let her have the room. Jenny is intrigued by him.
Jenny Lind (Grace Moore)
At dinner, Paul presents Jenny with a song and asks her to sing it. She refuses, but then he makes it a condition of having his room. When Jenny sings [It Is Destiny], Paul constantly corrects her style. After the song, Paul kisses Jenny, who slaps him. He says he kissed her because he has always wanted someone to sing his song like that. He adds that he fell in love with her the moment he saw her and that they have not met by accident. Paul leaves, but he assures Jenny that they shall meet again.
In Malmo, Jenny performs in Donizetti’s The Daughter of the Regiment [Rataplan]. During the performance, Jenny discovers that Paul is now a member of the chorus. She invites him to supper [Student’s Song]. Paul gets rid of Josephine, but Jenny says she cannot dine with him alone [Oh, Why?]. Paul reveals that, far from not knowing who she is, he has long carried her picture with him. He tells her again that he adores her, and Jenny admits she has been thinking about him since the inn. She says they must both be mad. She talks about marriage, but he says he could never be the husband of a great prima donna. Paul warns Jenny that one day the world will turn its affections elsewhere, but that he will always love her. She asks him to go.

Much later, in Italy at the end of a long tour, Jenny is about to perform Norma. She hears Rosatti, a famous Italian prima donna, get a rapturous welcome as she takes her seat in the audience. The performance begins [Casta Diva], with Paul also in the audience. An encore is demanded, but Jenny says she is exhausted and her throat hurts; she does not want to go back on. She is persuaded to sing again [Casta Diva], but her voice goes. The curtain is brought down and Jenny collapses. The crowd calls for Rosatti. Paul defends Jenny and a fight breaks out. Paul is struck hard on the head and passes out. Backstage, Jenny hears Rosatti complete the performance.
Later, Paul brings his uncle, the maestro Garcia, to help Jenny recover her voice. Paul is walking unsteadily. After Paul has left, the maestro accidentally reveals that his nephew’s sight has been impaired since the fight in the theatre. Paul will not get the help he needs because all he can think about is helping Jenny.
Back in Sweden [Swedish Pastorale], Jenny is with Paul, whose eyes have been bandaged for two months, following treatment. When the doctor removes the bandages, Paul pretends that he can see for the sake of Jenny, but confesses the truth to the doctor, who says the blindness will be permanent. Before Paul can tell Jenny the truth, she reveals that her voice has returned [It Is Destiny]. Paul slips away, leaving a note telling Jenny that he loves her but must go.
Jenny and Paul, following the operation intended to restore his sight
Jenny makes her debut in the United States, where she is promoted by P T Barnum. Paul is also in America. He is blind, performing his music in a bar. Olaf, a fellow Swede and friend of Paul’s, breaks into Jenny’s dressing room. He has brought one of his blind friend’s songs, hoping that Jenny will buy it and sing it. Josephine takes the song and throws him out. Jenny sees Paul’s name on the manuscript and realizes that he is blind. Jenny tells Josephine to find Olaf.
While Jenny sings [Lovely Hour], Paul is in a huge crowd outside the theatre who are listening through the open windows. Later, Olaf tricks Paul into meeting Jenny. She gently admonishes Paul for not telling her about his blindness, and they embrace.
