The action takes place under the Restoration, at the Château de Savigny, near Nerville, a devout and prudish little town in the Cotentin region. Doctor Torty is the doctor. He tells a story of which he is the only one to know the secret, that of a criminal couple, without any remorse. The pretty Hauteclaire Stassin, daughter of the master of arms, meets the Count of Savigny, married to the noble and languid Delphine. Madly in love with the count, Hauteclaire joined the castle as a servant. Shortly after, the countess died of poisoning. Will the guilty lovers go unpunished?
