Johanna, a young drug addict, falls into a deep coma after an accident. Doctors miraculously manage to save her from death's doorstep. Touched by grace, Johanna cures patients by offering her body. The head doctor is frustrated by her continued rejection of him and allies himself with the outraged hospital authorities. They wage war against her but the grateful patients join forces to protect her. This is a filmic and musical interpretation of the Passion of Joan of Arc.

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.
