Alain, a former mountain guide, decides to change his life and become a teacher. He finds himself faced with colorful ninth graders who are not interested in anything. Seeking to motivate them and bring them together, Alain decides to organize an outing... in the bowels of a glacier. The students discover a breathtakingly beautiful world of ice. The idea that this glacier could disappear is unbearable for them. Trained by Alain, the students throw themselves body and soul into a crazy project: to prevent the glacier from melting and nothing can stop them!
