The Soviet-Hungarian film version of the biography of one of the most talented composers of our time, the classic of the Vienna operetta - Imre Kálmán, known for all his music for operettas "The Csárdás Princess", "Countess Maritza", "The Circus Princess", "The Violet of Montmartre", "Die Bajadere" and many others. The music of Imre Kálmán has no equal in operetta for its festivity, “elegance”, and the refinement of melodics and orchestration.
