In this light and lovely romantic musical, a Hungarian woman attends a Viennese fair and buys a card from a gypsy fortune teller. It says that she will meet someone important and is destined for a happy marriage. Afterward she gets a job as a baker's assistant. She then meets a handsome army drummer who secretly dreams of becoming a famous composer and conductor. Unfortunately the military forbids the young corporal to create his own music. But then Ilonka secretly sends one of the drummer's waltzes to the Austrian Emperor with his weekly order of pastries. Her act paves the way toward the tuneful and joyous fulfillment of the gypsy's prediction.
