Peter Grimes lives from fishing. Raw and recluse, he finds himself at odds with the local community who accuse him of brutality towards his young apprentices and blames him for the death of one of them. A few friends stand up for him - Ellen Orford, a widow whom he wants to marry, Balstrode a retired sea captain, and an apothecary Ned Keene - but Grimes remains a mysterious figure. What really happened to his missing apprentice, and was he involved?

Young Renata hears voices. Since her childhood, she has been visited by a fiery angel with sublime radiance. Mad about him, gone in search of him since he abandoned her, she meets on her way the knight Ruprecht who, out of love for her, will try to tear her away from this carnal possession. From tavern to convent, between scenes of spiritualism or exorcism, collective hysteria or burlesque humor, nothing is lacking at L'Ange de feu.
