The film, which co-starred and was co-written by sexologist Magnus Hirschfeld, refers to Hirschfeld's theory of "sexual intermediacy". The theory places homosexuality within a broad spectrum comprising heterosexuality, bisexuality, transgenderism, and transvestism (a word invented by Hirschfeld). The film's protagonist first meets his blackmailer at a costume party, and the blackmailer also frequents a drag club; these scenes are the earliest film footage of gay men and lesbians dancing. The film was initially shipped in 40 copies throughout Germany and the Netherlands by Oswald, and it was shown for nearly a year before the authorities stepped in and banned public screenings, allowing it to be shown only to doctors and lawyers. The Nazis destroyed the majority of the prints and only one copy of the film is known to exist.
