"Children don't care about differences in social class, skin color, or religion, so why does Paul and Sofia's 9-year-old son Corentin only have friends like him? And what happens when all of his friends leave for a Parisian private school? [...] Michel Leclerc’s newest comedy drama La Lutte des Classes amusingly explains uphill classism and liberalism, supplying everyone with a good moral compass."
