Marie Bernais, who lives in a small Breton village, possesses a beautiful singing voice that her puritanical father, Jules, believes is a gift from the devil. She falls in love with minister Raoul Nieppe, but his snobbish parents disapprove, prompting the despondent Marie to throw herself into the ocean. She is rescued by Hector Remey, a once famous singer turned puppeteer, who is in town for the carnival. Hector is impressed with Marie’s voice and takes her to Paris, France, where she become a successful singer. Marie later finds love with wealthy Gaspard Prevost, who is trapped in a loveless marriage. Raoul learns of the romance and invites Marie to sing for the departing soldiers in their native village. She consents, even though the performance could ruin her voice. Following Marie’s arrival, Jules places a curse on her and dies soon after. In her sadness, Marie has a religious epiphany, which Raoul attempts to exploit by insisting that she end her romance with Gaspard. She rejects the deceitful minister and, having lost her singing voice, inherits her father’s job as lighthouse keeper. Following the death of his wife, Gaspard travels to the village to reunite with Marie.
