A bored Marquise holidays with her two young children on the French Riveria. She becomes taken with the photographer she hires to photograph her and her children; heady with the way he looks at her and the power she has over him, she falls into an adulterous secret affair - until he expresses his determination to follow her back to Paris and continue the affair there, leading her to an unplanned and desperate measure to be rid of him that she can never escape from. It's a fascinating story of a psyche, of what makes us do certain things and how the consequences can affect ours lives forever.
