That's a better title than the one they went with, which refers to the character played by Depardieu, because the film is about Huppert's character, who is 25 in this film and already an accomplished actress.
This film, like most dramatic films (and even some comedies), is about poor choices and their consequences. Nelly clearly made a bad decision marrying Andre, a boring, jealous, possessive jerk who overreacts and becomes violent when she so much as looks at other men. Andre may or may not love Nelly but he clearly has no clue what she needs or how she wants to be loved.
Small wonder that Nelly is fed up and dumps Andre. But for womanizing bad boy Loulou, just our of prison, with no visible means of support, and still involved in silly heists with his criminal pals? Hmmmm ...
But wait! It gets better ... um ... worse: Loulou gets Nelly pregnant. Apparently, both missed the class in high school where they tell you about safe sex, or just plain don't care. What happens to the pregnancy is predictable after Nelly visits Loulou's family and realizes this "package deal" is not an improvement over life with Andre -- though I would say the film understates the effect of the abortion on Nelly. There is no happy ending; quite the contrary, we are left with the clear impression Nelly's life will be, as Hobbes says, "nasty, brutish, and short." What is a woman to do? Yes, indeed.
A brief word about the subtitles: They are bare bones; not wrong, mind you, just leave out subtleties that would have added context to the story.
