At a tough inner-city middle school in Paris, a dedicated teacher named Mr. Marin (Francois Begaudeau) begins the new term. Taking on a class comprised of a melting pot of modern-day French society, he pushes and prods his pupils while striving to gain their respect. And as each side challenges the other over issues both academic and personal, Mr. Marin and his students are about to get an education they'll never forget.
