Two sisters, two different destinies. In Final Transgression, 85-year-old Caroline Aubry tells the tale of the tragic wartime destiny of her beloved younger sister, Séverine. From their humble beginnings in a hamlet in the southwest of France to a château where Séverine becomes the protegée of the beautiful countess who employs their parents, their trajectories differ. After they move to Paris, the pragmatic Caroline becomes a successful designer and the high-spirited Severine marries a rich jeweler. When WW2 breaks out and her collaborationist husband betrays her, the headstrong Séverine flees to the chateau and the countess –– in spite of warnings about the risk of traveling to an area that is a fierce battleground for rival groups of résistants, Nazis and collaborators. Séverine is beautiful, intelligent but obstinate – and that obstinacy will ultimately seal her fate. The end of the war in France was a time for settling scores. Séverine, an ordinary woman living in extraordinary times, unwittingly hands the hangman’s noose to her enemies in one egregious act—her final transgression.
