Céline is 17 years old. She is one of the rare girls of her professional lycée to run for a diploma of house painting. She lives in a difficult area in the Parisian suburbs with her family. What attracted Stéphan Moskowicz was her enthusiasm, the way she bumps into life and bounces. So he follows her in her daily life. But this film is not just the look of a director upon his subject – it is the fruit of a very narrow collaboration between the documentary department and the youth department of France 2, and between a young girl and a film director. They have built this film together, and Stéphan Moskowicz has offered his professional experience to help her tell her own story.
