This movie is about a brothel c.1895/ 1900 in Paris. It is a high-end establishment run by a Madame. The film is very descriptive and perhaps a bit slow, showing us the life of the girls, with their clients and when not working.
What is interesting is that it is very much a women's society, despite the fact they are all there, ostensibly, to serve the selfish needs of men (and rich men). But the film is made from the point of view of the women, which gives it an interesting angle.
The movie is not a masterpiece, however. Somehow, it is a bit slow and demonstrative. Also, the pop music occasionally used to accompany the story grates, in my view. And the very last shots at the end of the movie are tagged on as an ideological statement rather than anything else.
