Goodbye, children

France, 1944: As Paris has become too dangerous, 11-year-old Julien reluctantly returns to his boarding school after the Christmas holidays. Three students, including Julien's roommate Jean Bonnet, are new and are teased and mocked by the other students. Initially, Julien finds it hard to warm up to Jean, especially since he is an outstanding student. However, a friendship gradually develops between the two. The boys try to navigate their daily lives, but the reality of war does not spare the seemingly idyllic world of the boarding school: food is scarce, the children are freezing, and during air raids, classes are hastily moved to the cellars. Julien suspects that his new friend is hiding a secret: Jean is Jewish. One day, the Gestapo shows up at the door.
