Jeanne begins as a medieval French peasant woman, newly wed to Jean. Their marriage instantly confronts feudal oppression when they cannot pay an exorbitant marriage tax demanded by the local baron. This culminates in her brutal gang rape by the baron and his courtiers during the wedding celebration, a violent act establishing the trauma defining her early story. After the assault, she returns to Jean; he reacts with conflicted emotions, first suggesting they move forward before attempting to strangle her in distress.

Isolated and traumatized, Jeanne encounters a phallic-shaped spirit claiming to be an extension of her own desires. This entity, later revealed as Satan, offers power in exchange for submission. Initially resisting surrendering her soul, she bargains with her body, leading to further non-consensual encounters where the spirit grows in size and influence alongside her escalating demands. These transactions grant economic prosperity, enabling her success as a moneylender and weaver—notably producing green fabric symbolizing the Devil’s influence and her burgeoning authority. Her financial rise elevates Jean to tax collector, but his failure results in brutal mutilation by the baron, further fracturing their bond.

Jeanne’s social ascent provokes the baroness’s envy, who orchestrates her vilification as a witch. A violent mob assaults her while Jean, intoxicated and passive, fails to intervene. Forced into forest exile, Jeanne fully embraces Satan’s pact, surrendering her soul for magical abilities. Contrary to her expectation of becoming grotesque, she emerges with heightened beauty and supernatural power over nature. Satan frames her rage and hatred as sources of radiant strength.

Returning to a village ravaged by plague, Jeanne uses poisonous yet medicinal belladonna flowers to heal the afflicted. This perceived miracle garners widespread devotion. She presides over communal rites emphasizing sexual liberation and emotional release, consolidating her influence. Her powers attract the baron, who, through Jean, offers nobility for her knowledge. She rejects this, declaring intent to possess "the entire world," leading to condemnation.

Captured and sentenced to death, Jeanne burns on a cross-shaped stake. Jean attempts rescue but is killed by the baron’s guards. During the execution, the faces of female onlookers morph into Jeanne’s visage, visually affirming the priest’s warning that a witch’s spirit spreads "like sparks from a fire." Centuries later, her legacy links to the French Revolution through textual reference to women leading the uprising and an image of Eugène Delacroix’s *Liberty Leading the People*. Her journey frames sexual trauma, alignment with demonic forces, and martyrdom as catalysts challenging feudal and patriarchal structures, positioning her as a paradoxical figure of victimization, empowerment, and historical rebellion.
