Vicky Krieps (Phantom Thread, Bergman Island) gives another riveting performance as Camille, a woman on the run from her family for reasons that aren’t immediately clear. Widely renowned as an actor but less well-known here for his equally impressive work behind the camera, Mathieu Amalric’s sixth feature directorial outing—his most ambitious to date—is a virtuosic, daringly fluid portrait of one woman’s fractured psyche.
