Set in the 1930s, this film from Luxembourg stars Emmanuelle Devos as a mother of three young children who slowly comes to suspect that her foundry-worker husband (Clovis Cornillac) is having an affair with her beautiful younger sister. Initially she avoids confronting the situation, but her fierce devotion and attachment to her spouse lead her to make a destructive compromise. While the outcome is never really in doubt, director Frederic Fonteyne illuminates the wife's inner world with a rich sense of atmosphere, and Devos' riveting performance manages to convey every shift in her character's suppressed emotional life with the subtlest of gestures and expressions. In French with subtitles. 108 min.
