Thirty-year old Marie is enjoying life. She has a husband, whom she adores with every ounce of her being (and who equally adores her), and she's easily pleased by the smaller things in life - the drag of a cigarette, a hotel balcony, the scattering of light across the surface of the sea. While on holiday, Marie spots a young man lying on the beach and is instantly drawn to him. Their connection develops into a passionate and intensely innate love affair, opening a window into Marie's untapped desires, which she begins to explore with vibrant immediacy and leads her to question her every decision.
