The beautiful Helene (Catherine Deneuve) works in a hospital as an anesthesiologist and so when she accidentally hits Gilles (Patrick Dewaere) while driving her car, she can jump out and know exactly what to do to make sure he is not seriously hurt. The two start off a relationship based on this "chance" meeting, though the inauspicious beginning should have served as a warning. Gilles does not do very much except live in a room in his family's hotel and hang out. His lethargic approach to life is an anesthetic in itself, and since Helene is still mourning the death of her former lover a few years before, she is not overly anxious to start a new romance. The two of them go back and forth in a cat-and-mouse game until Helene tires of going nowhere and decides to leave for Paris. Considering how difficult it is for Gilles to rise to any action, it seems that Helene may remain alone unless she runs into someone else.
