Original title: La Proie pour l'ombre

Anna, twenty-seven, married to building contractor Eric, refuses to live in his wake. Craving independence, she can exist through the art gallery she runs, but isn’t this occupation a mere wholesome distraction? When she meets Bruno and becomes his lover she thinks she will find fulfillment only to realize that she is just another plaything in a man’s hands.
