Isabelle Huppert is great in this movie, with her blunt dialogue, but you have to like essentially plotless French films. Fortunately, I love them. It starts off as her husband of many years announce he is moving in with another woman. They are both philosophy teachers, with a great love of books.
The film meanders through other events. The most interesting is her visits to a former student and protegé in the countryside, where he is hanging out with a group of anarchists. But it is not a romantic liaison, just a visit. Just as it would be. And life goes on.
