In Vienna, a new jazz club featuring American trumpeter Buzzy Bellew threatens the existence of its neighbor, the Waltz Palace, run by Franz Strauss and featuring his granddaughter, singer Elsa. Smitten by Elsa, Buzzy hides his identity and association with the club -- whose owner intends to buy out the Palace property. When Elsa accidentally learns who Buzzy really is, it appears he may have to return to America alone.
