Sandrine Bonnaire plays Anna, a depressed and distracted woman who is visiting a psychiatrist (Dr Monnier, played by Michel Duchaussoy) for the first time. Apparently by mistake, she enters the adjacent office of William (Fabrice Luchini), a tax lawyer, and, without more ado, assuming he is the therapist, launches into a recitation of her problems. William is too uptight to stop her unburdening herself - and then she abruptly leaves.
