The story is about a young woman living in Paris, in the Bastille neighborhood, who has lost her cat. Through the pursuit of the cat, the film lets the spectator discover the contrasts of the district, which is evolving from a typical Parisian district to a modern and young district and the contrast between its inhabitants, among them a nice simpleton and the old women who are bored. In fact it is the story of a village in a large city, Klapisch shows once again the behaviour of an individual inside a group, as he did in ''Le péril jeune'' or ''Riens du tout''. This time he has succeeded in joining together actors, theatre actors and residents of the district, creating a credible atmosphere that is probably the reason for the success of this film outside France.
