In the first of Hartl's two Mozart biographies, Hans Holt plays the robust and dashing composer who, in keeping with the spirit of the film's time of origin, sets out into the world like a soldier of art after his falling out with the Salzburg authorities. Instead of conquering lands, he conquers the hearts of young ladies, like one of his most famous creations.

Shortly before the end of the war: Disillusioned Austrian soldiers crammed into a barracks in a prison camp welcome a new arrival who has nothing better to do than rave to the men, who have been separated from their homeland for years, about his Viennese lover. When the womanizer mentions the name of his latest love affair, Manhardt, her husband, jumps at him in outrage; the adulterer falls and dies. Acquitted of murder and returned to Vienna, Manhardt cannot get over his Anni's infidelity. Friends and a second fateful coincidence help.
