A middle-aged Parisian who teaches English literature (Charlotte Rampling) loses her husband (Bruno Cremer) when, vacationing with her in the country, he goes off for a swim and never comes back. This impressive feature by Francois Ozon (Water Drops on Burning Rocks) is less concerned with solving the mystery than with charting the wife's gradual adjustment to the loss, something it handles with both confidence and a remarkable feeling for psychological nuance. Rampling is extraordinary, and the screenplay (by Ozon, Emmanuelle Bernheim, Marcia Romano, and Marina de Van) gives her plenty to work with. Others in the cast include Jacques Nolot and Alexandra Stewart. In French with subtitles. 95 min.
