Everything is lousy about this production except the story. The direction is despicable, the actors can't act, the result of the editing is a mutilation, and the happy ending is a joke. However, most of the ladies are quite good and convincing enough, and it's their film. It's their story this film is here to tell, and it's a great story involving many stories. Not only are several of these girls brave freedom fighters who don't hesitate to wage their lives when there is no other choice, but there are a number of great tragedies hinted by their stories, the most important of which is the mother who finds her daughter.
Forget about the Japanese and German officers, they are all caricatures, and you can see that the actors themselves don't believe in the almost ludicrous roles they are playing. This is a women's drama, and that's all that matters.
Also the music is very well made and gives at least a gilded frame to something that could have been an engaging masterpiece, if the direction and the male actors had been better.
The fact is, that there were rests of German officer cliques stranded in China (here Shanghai) and elsewhere after the surrender of Germany and before the Japanese final surrender who still believed in their absurd Reich, many escaped alive out of Germany and immediately started planning for the next Reich, - of course, they did not succeed, as they also fail in this film, but their plans and visions were enough alive to keep cliques like this active to the last.
Pity that such a good story should be made such a bad film of, but then at least you can take care of and mind what's memorable in it, and it is never wrong to point out the women's cause.
