At the Ursuline convent in Loudun rumours of a local priest, the charismatic and frivolous Father Urbain Grandier, have reached the hunchbacked prioress Jeanne. Her imagination is peaked, and one night she has an eerie vision: Soldiers carry the priest, badly mangled and with a rope around his neck, to her bedside. Here, Grandier is accused of a crime against Jeanne, to which he pleads innocent.

Jeanne writes to Father Grandier, inviting him to become the convent's new confessor, but Grandier politely declines. Following this rejection, Jeanne has another vision: She sees Grandier embracing a young woman.

Grandier does indeed have a weakness for women. He is having an affair with Ninon, a young widow whom he met when he was sent to console her following the sudden death of her husband, and he starts a relationship with Philippe, a girl who declares her love for the priest at the confessional. Gossip spreads about Grandier's special way of offering pastoral care to his female parishioners. Adam the chemist and Mannoury the surgeon are particularly offended and decide to join forces to conjure up evidence of Grandier's broken vow of chastity.

Grandier also becomes involved in the increasingly inflamed political situation in Loudun. Cardinal Richelieu and his confidant Father Joseph, “the Grey Eminence”, wish to enhance their power in France by tearing down the fortifications of every French city and town. D’Armanac, mayor of Loudun, is against this initiative, and Grandier declares that he will support d'Armanac. D'Armanac warns the priest: So far King Louis XIII stands by d’Armanac against Richelieu in this matter, but should the king go back on his word, Grandier's stance may prove dangerous. Grandier forms another dangerous alliance of a more personal kind as he secretly marries Philippe. It is Grandier's hope that love and marriage will show him a way to God that he has failed to find in his lonely state.

Jeanne confides in the new confessor of the Ursuline convent, Father Mignon, telling him that Grandier is in league with Satan and is possessing her. Horrified, Mignon sends for Father Barré, a priest from Chinon, who is an expert on the power of evil and exorcism. Barré begins his treatment of Jeanne. During an exorcism he apparently manages to communicate with a demon lodged deep in Jeanne's stomach, claiming to serve Father Grandier. As Jeanne is later questioned, she attests to having participated in satanic orgies along with other ursuline nuns and several demons, all under the command of Grandier.

The bizarre exorcisms and Jeanne's colourful confessions are followed with great interest by Jeanne’s and Grandier’s surroundings. Adam and Mannoury as well as Baron de Laubardemont, an emissary of Richelieu, are eager to gather compromising information about Grandier, and several Ursuline nuns back up Jeanne’s claims of demonic possessions. Only the town judge de Cerisay and Prince de Condé, an envoy of the king, remain sceptical. On the advice of Prince de Condé, the archbishop forbids any further exorcisms in Loudun, and Prince de Condé manages to expose the exorcisms as fraud.

Their efforts do not, however, suffice to prevent Grandier's increasing disfavor in Loudun. The king falters in the matter of the fortifications, thus exposing Grandier to the enmity of the menacingly powerful cardinal, and Grandier loses Philippe, too: She is pregnant, and as Grandier cannot possibly own the child, he must let Philippe find herself another husband and provider. At a Counsil of State meeting, the king, Richelieu, Father Joseph, de Laubardemont, and de Condé discuss the case of Grandier, his notorious love life and the alleged demonic possessions. De Condé attests to Grandier's innocence, but the general sentiment is against him. Richelieu seals Grandier's fate with a quote from St. Chrysostom: ”The devil cannot be believed even when he tells the truth.”

Grandier is banned from his church and arrested as an accomplice of the devil. A mob assembles outside Grandier's prison cell in which the terrified priest spends a restless night. De Laubardemont shows up and commands Grandier to strip and to shave off all his hair, before ordering for Grandier's fingernails to be torn out. At his interrogation Grandier confesses to having lived a life of the senses, but he maintains that he is innocent in regards to his supposed alliance with Satan, even as he is threatened with torture.

Jeanne is kept awake at nights by the mysterious sounds of weeping. Driven to despair she wants to kill herself, but her Ursuline sisters assure her that the ghostsly sounds are merely the work of the diabolical Grandier who wishes to torment his informeress. Meanwhile, Grandier is brutally tortured, but continues to plead innocent. Finally, he is carried off for his execution, a rope around his neck. From the scaffolds Grandier prays for God to forgive his enemies. While he suffers a painful death, Jeanne appears. She kneels down and prays.
