Barny, Emmanuelle Riva, is a young mother raising her daughter France in a quiet town high in the French Alps, living under the Occupation. She keeps busy by correcting assignments for a Parisian correspondence school that has moved to the town, doing what she must to get by after her Jewish husband was killed in the war. Physically and emotionally strained, Barny feels a restlessness she cannot ignore, and this unease leads her to notice Sabine Levy [Nicole Mirel], the administrative secretary at the school, in a way that goes beyond professional courtesy.
As a jaded, lapsed-Catholic who has drifted into atheism and militant communism, Barny treats religion with a sharp skepticism. Yet she and a circle of Jewish and communist friends decide to baptize their children as a protective measure against the occupying troops. This decision sets in motion a reckless personal experiment: Barny enters a local church to perform a fake confession, hoping to provoke a reaction. Instead, she meets Léon Morin, a young curate whose unassuming demeanor makes him seem approachable rather than doctrinaire. In their first encounter, she provokes him with questions about faith, only to be drawn into a calm, patient theological discussion where he offers to lend her books and they arrange to meet again. She leaves the church unsettled, as if a door she did not know existed had opened.
To shield France from danger, Barny sends her daughter to live on a secluded farm, and soon she begins to visit Léon regularly. She is struck by his moral steadiness and the quiet conviction with which he approaches faith, and as their conversations deepen, she finds herself increasingly drawn to his interpretations of scripture even as she guards her own beliefs. The town grows tenser as German forces consolidate control and push Italians out, and Barny and Léon do what they can to help neighbors in distress. A turning point comes when Sabine Levy’s brother is arrested by the Gestapo, an event that ages Sabine in a matter of weeks and intensifies the emotional toll on everyone involved.
Barny’s spiritual journey becomes more complex as she returns to the church, and Christine Sangredin [Irène Tunc], a coworker who has also drifted into collaboration, becomes a new connection through which people seek Léon’s guidance. The presence of Léon continues to impress Barny, and she begins to see him not just as a voice of theology but as a compassionate man whose presence stirs feelings she had not anticipated. The relationship between conviction, desire, and duty threads through their interactions, even as the war continues to cast its long shadow over the town.
When the Germans finally abandon the town, France returns to live with Barny, and the possibility of a straightforward coupling between Barny and Léon recedes. Barny asks Léon if he would marry her if he were a Protestant minister; he does not answer, and the moment unsettles them enough to pause their closeness. He later returns to discuss theology as though nothing had occurred, leaving Barny both drawn to him and wary of the implications. He tells her that she must come to him at the church to confess and receive penance if she hopes to continue their conversations, a request that reframes their dynamic in terms of spiritual duty rather than romance.
Léon learns that he is being transferred to another parish, a news that casts a long shadow over their fragile connection. In a quiet, intimate moment, they are interrupted by the girl France listening at the door, and Léon’s attempt to maintain boundaries underscores the tension between their evolving feelings and his vows. He escorts Barny back to reality and then to bed, and Barny contemplates the ironies of fate: the man who has become central to her life arrived not to disrupt her life irreparably but to offer a path of solace for her daughter.
As the correspondence school prepares to move back to Paris, the town braces for a farewell. Barny and Léon acknowledge the end of a shared era, and he hints at a future beyond their current lives. On the eve of his departure, they share a final, poignant exchange, and he promises to meet again in another life. Barny leaves with a mix of gratitude and sorrow, her faith unsettled, her heart stretched, and her resolve to protect those she loves reaffirmed as she steps back into the world awaiting her.
