The film's narrative culminates in Joan's final, agonizing decision. After enduring relentless interrogation and being shown instruments of torture, Joan is taken to the prison courtyard where a stake is being prepared. Overwhelmed by fear, she finally breaks and agrees to sign a confession, recanting her divine claims. The judge condemns her not to death, but to life imprisonment on bread and water.
In her cell, as a jailer crudely shaves her head, the full weight of her decision dawns on her. This act of humiliation serves as a moment of terrible clarity. She realizes she has saved her mortal life at the cost of her soul and her divine mission. Filled with renewed conviction, she tells the jailer to summon the judges and courageously recants her confession, choosing death over a life of spiritual falsehood.
She is then taken to the stake. The film portrays her execution with harrowing realism. As the flames rise, the crowd of onlookers, who had been watching with a mix of mockery and curiosity, are overcome with grief and horror, realizing they are witnessing the death of a saint. Their grief turns to rage, and they begin to riot against the English soldiers, who brutally suppress the uprising. The hidden meaning becomes clear: Joan's physical defeat is her spiritual triumph. Her martyrdom ignites the spirit of the people, ensuring that her cause will live on. The final intertitle declares that the flames sheltered her soul as it rose to heaven, cementing her legacy as a martyr and the heart of France.
