During the winter of 1943–44, Julien Quentin, a student at a
Carmelite boarding school in occupied France, is returning to school from vacation. He acts tough to the other students, but is actually a pampered boy who misses his mother deeply. Saddened to be returning to the monotony of
boarding school, Julien's classes seem uneventful until Père Jean, the headmaster, introduces three new pupils. One of them, Jean Bonnet, is the same age as Julien. Like the other students, Julien at first despises Bonnet, a socially awkward boy with a talent for arithmetic and playing the piano. One night, Julien wakes up and finds Bonnet wearing a
kippah and praying in
Hebrew. After digging through his new friend's locker, Julien learns the truth. His real name is not Bonnet, but Kippelstein. Père Jean, a compassionate, sacrificing priest at the school, had agreed to grant secret asylum to hunted Jews. After a game of
treasure hunt, Julien and Jean bond and develop a close friendship. When Julien's mother visits on Parents' Day, Julien asks his mother if Bonnet, whose parents could not come, could accompany them to lunch at a gourmet restaurant. As they sit around the table, the talk turns to Julien's father, a factory owner. When Julien's brother asks if he is still for
Marshal Pétain, Madame Quentin responds, "No one is anymore." The
Milice arrive and attempt to expel a Jewish diner. When Julien's brother calls them "
Collabos", the Milice commander is enraged and tells Madam Quentin, "We serve France, madam. He insulted us." But when a
Wehrmacht officer coldly orders them to leave, the Milice officers grudgingly obey. Julien's mother comments that the Jewish diner appears to be a very distinguished gentleman. She insists that she has nothing against Jews, but would not object if the
socialist politician
Léon Blum were hanged. Shortly thereafter, Joseph, the school's assistant cook, is exposed for selling the school's food supplies on the
black market. He implicates several students as accomplices, including Julien and his brother, François. Although Père Jean is visibly distressed by the injustice, he fires Joseph but does not expel the students for fear of offending their wealthy, influential parents. On a cold morning in January 1944, the
Gestapo raid the school, searching for Jean Kippelstein. As his classroom is being searched, Julien unintentionally gives away Bonnet by looking in his direction. As the other two Jewish boys are hunted down, Julien encounters the person who denounced them, Joseph the kitchen hand. Trying to justify his betrayal in the face of Julien's mute disbelief, Joseph tells him, "Don't act so pious. There's a war going on, kid." Disgusted, Julien runs off. Jean and Julien exchange books, a shared habit of theirs, as they pack away their belongings due to the closure of the school. As the students are lined up in the school courtyard, a Gestapo officer denounces Père Jean's actions and calls French people weak and undisciplined. A moment later, Père Jean, followed by the three Jewish boys in single file is led away across the school yard. One by one, as the priest passes through their midst, the students spontaneously call out to him, "
Au revoir, mon père!" He pauses and half turns towards them and gives a loud reply: "
Au revoir, les enfants! À bientôt!" Jean is the last to exit the school grounds through a metal door in the garden wall. As he steps through the doorway, he glances back for a moment toward Julien, and Julien gives him a timid wave in return. The film ends with an older Julien providing a voiceover epilogue, in which he mentions that Bonnet, Negus and Dupré died at
Auschwitz, whereas Père Jean died at
Mauthausen; the school reopened in October. He explains that although more than 40 years have passed, he will remember every second of that January morning until the day he dies. ==Cast==
