In the quiet village of Ambricourt, the Claude Laydu plays the new parish priest who keeps a diary, laying bare his insecurities about a challenged faith, his inexperience, and a health that grows steadily worse. Only one person, Miss Louise, Nicole Maurey attends daily mass, and the priest’s undiagnosed stomach ailment leaves him living on a stark diet of bread, wine, and sugar. He hopes to win the village over by proposing a Catholic youth club and a sports program, asking for funds from the Count of Ambricourt, Jean Riveyre. But his mentor, the experienced priest of Torcy, Adrien Borel, counsels him to project strength rather than seek affection, insisting that true obedience comes through respect.
As time passes, the priest finds himself drawn into the Count’s fraught family drama. The Count and Countess have two children—the teenage girl Chantal and a younger boy who died years earlier. The tragedy leaves the Countess embittered and withdrawn from God, while the Count begins an affair with Louise, Chantal’s governess. Although both the Countess and Chantal know of the affair, the Countess tolerates it while Chantal grows resentful. Louise complains to the priest that Chantal mistreats her; the priest agrees to speak with the Count, but the Count welcomes him at first only to grow cold when the conversation turns to Chantal and Louise, seemingly hoping the priest will look the other way. Louise subtly suggests the priest seek a transfer. As the priest’s health declines, he struggles to hold onto his faith, wondering if God has abandoned him.
A fellow cleric, the priest of Torcy, urges him to seek help from Dr. Delbende, who examines the priest’s abdomen but offers no clear diagnosis. One day, Dr. Delbende takes his own life, a tragedy the village views with suspicion and sorrow. The priest of Torcy explains that Delbende’s loss of faith and fear of judgment pushed him to despair, arguing that a good man can fall into mortal sin without being rejected by God. Meanwhile, to obscure Chantal’s presence, the Count and Louise orchestrate plans to send her to boarding school. When Chantal ends up seeking the priest’s counsel, he senses her suicidal distress and, following his mentor’s grim guidance, pressures her to surrender her suicide note. Though she yields the note, her fear is palpable, and she resolves to bring him down.
In a bid to shield Chantal, the priest visits the embittered Countess on her behalf and persuades her to seek reconciliation with God, insisting that “God is not a torturer” and that Jesus already died for humanity’s sins. That night, the Countess sends a note of thanks to the priest and dies of a heart condition. Chantal overhears the exchange and falsely tells her father that the priest drove his wife to despair, prompting the Count to seek a church investigator to question the priest. The priest refuses to exonerate himself by using the Countess’s letter, implying it is protected by the seal of confession.
Chantal then taunts the priest, vowing to “sin for sin’s sake,” but she eventually confesses that she was moved by the comfort and clarity the priest offered her mother. She asks for his “secret,” but the priest laments that it is “a lost secret,” suggesting that it will be found and then lost again, carried on by others after them.
After hemorrhaging, the priest travels to Lille for help and is diagnosed with terminal stomach cancer. He seeks out his seminary classmate Dufrety, once a priest who now lives with a woman out of wedlock, and collapses in Dufrety’s flat. Dufrety’s partner cares for him until the end. Before dying, the priest asks Dufrety for absolution. Dufrety questions whether, as an ex-priest, he should perform the rites, but the priest insists that it does not matter and that “All is grace.”
