Nadja is a guest student, who stays at Cité Universitaire and visits the Sorbonne, while preparing a thesis on Proust. Besides her student life she likes to stroll about Paris, to explore the variety of this wide and open city. She knows Saint-Germain-des-Prés well, but feels more comfortable among the bohemians, painters and writers in Montparnasse. Sometimes she wants to get out of the narrow area of intellectual Paris. She then goes to the park Buttes Chaumont and the working class neighborhood of Belleville. There she discovers a world that is simpler and more characteristic of France. This helps her to distance herself from everything that was superficial in her life. She thinks that Paris teaches you more about yourself than you learn about the city.
