Nora (Emmanuelle Devos) is a 35-year-old art gallery director and single mother struggling to rise above tragic circumstances—a late husband, a failed second marriage and a lover’s suicide—through her successful career and marriage to a wealthy businessman. Ismaël (Mathieu Amalric), her ex-husband, is a disheveled, neurotic musician who descends into a comic nightmare when he is mistakenly committed to a mental hospital. He faces off against the steely clinic psychiatrist (Catherine Deneuve, in a scene-stealing cameo), but his eccentric antics—including an in-house pharmacy raid with his drug-addicted lawyer–earn a ten-day stay that may leave him worse off than when he entered. On discovering that her father is terminally ill and fearing for the future of her young son, Nora tracks down Ismaël at the institution to enlist his help. A series of intimate revelations and reversals further connects these disparate lives, offering several enigmas, as well as a rich examination of love, memory, mental health, and family responsibility.
