A Japanese doctor, on a secret mission to Paris for his country, becomes romantically involved with a cabaret singer at a Parisian nightclub.

His entire mission is put at risk when he kills a rival for her love, a French journalist and blackmailer.

In Germany the film was banned for several reasons, particularly what was perceived as the unflattering portrayal of Europeans in contrast to the noble Asian characters.

The censors were also concerned that the incompetence of the French justice system would be taken by audiences to mean the German one, undermining their faith in it.

It is possible that Wiene, who had left for Budapest in 1933 following the Nazi rise to power, did not personally work on the new version.
