While Judge Bertaud suffers a cardiac arrest at the Palais de Justice, Boris Delcourt, who has just arrived in Marseille, is forced to replace him immediately in the case of Adèle Lebas, a teenager accused of kidnapping the daughter of his father's ex-lover as revenge. Moved by this affair, Constance Meyer insists on reopening the Hervé Lebas case, who, found guilty of the murder of his wife, has been claiming his innocence for seven years. Meyer manages to convince the new examining magistrate to listen to the prisoner.
