 All levels of society are depicted as pitching in together, with the heroine coming to know those of much lower social level in the course of the film.Hanna learns thereby to overcome her snobbishness, manifested in her singing for wounded soldiers.The depiction of Zarah Leander was also unusual, in that in this film she wore ordinary day clothes, lived in a normal Berlin rented flat and even travelled on the U-Bahn.
