Sois sage (2008)

There's something strange about Nathalie, the girl on the brink of maturity. She regularly causes uneasy situations by coming up with all kinds of dubious stories: that her handball-playing Spanish fiancé has had an accident, that she has a relationship with a lawyer in London, that she likes to cut the nails of her piano-playing married boyfriend, that she is really called Eve. In the meantime, she works for a baker in a village in the French countryside. She spies on an older married man with a small child in a mansion. Slowly but surely, the mystery unfolds.
