The young opera singer Carla is in love with the talented young composer Michele, who wants to make it big with classical music and writes his first opera, "The Return of Odysseus," for Carla. But Carla is more successful than he is and gets a gig at La Scala in Milan. Through her connections, she manages to find a publisher for Michele's opera. But when Michele learns what the publisher really thinks of his work, he leaves and abandons Carla. A year later, Carla finds Michele again. He has since become a sought-after composer, but is embittered because he is only successful with pop songs. His new revue "Dream Music," a reworking of his opera, is about to premiere. Carla then arranges for Michele's original opera to premiere in Budapest with her in the lead role.
