Set before the French Revolution, the novel depicts the coming of age of a nobleman named Bernard Mauprat. The story is narrated by the old Bernard in his country home many years later, as told to a nameless young male visitor. Bernard recounts how, raised by a violent gang of his feudal kinsmen after the death of his mother, he becomes a brutalized 'enfant sauvage'. When his cousin Edmée is held captive by Bernard's 'family', he helps her escape, but elicits a promise of marriage from her by threatening rape. Thus begins the long courtship of Bernard and Edmée.
