A dramatic, wounding film on famous sexologist Dr Magnus Hirschfeld, Jewish, gay, and a socialist. In 1897, he founded the first gay political group in history. Also, in Berlin, he opened his Institute of Sexual Sciences in 1920, unique and much commented the world over. Hirschfeld died in exile, in France, in 1935, two years after having had all of the work of a lifetime destroyed by the Nazis.

     The script reveals Hirschfeld's personality and experiences by means of the main characters in his life: from impossible love for Baron von Teschenberg to the happy years spent with young Karl Giese; of the struggle with the main opponent to the gay cause, rightist author Adolf Brand, to the support of his guardian angel transvestite Dorchen, a character of great intelligence and courage. Karl Giese committed suicide in 1938, in former Czechoslovakia, escaping from the Nazis.

     Dorchen's whereabouts are unknown. "The Einstein of Sex" was the name given to him by the American newspapers, in 1931. Asked about the comparison, he answered: "I think it's very good, but it would have been better if it described Einstein as "The Hirschfeld of Physics."
