Madame Gerve is a famous opera singer at the prime donna at the Opera Comique in Paris. When the French Prime Minister proposes marriage, however, she refuses and then sings at a benefit for war orphans. It`s there that she encounters two men from her past--Karl Wertz, the German ambassador to France whom she knew during the war when he was a German officer and his unit occupied her village, and Phillippe Sardonia, a Frenchman who is her former lover. Both men try to rekindle their past relationships with her, but she has a secret that she doesn`t want either man to know about.
