Once In A Lifetime 2014

This is the toughest high school class Ms. Gueguen (Ariane Ascaride) has ever taught, but Ms. Gueguen is not an ordinary history teacher. On the first day of school, Ms Gueguen forbids her students from caps, earphones, and chewing gums in class. Impulsive, self-centred and materialistic, her students do not seem "reformable" at all. But Ms. Gueguen sees hope in them and is determined to "educate" them. She compels her students to participate in a national high school competition on the theme of "Children and Teenagers in Nazi Concentration Camps". Will the lives of her students be transformed?
