Anna Benz, an American in her late-thirties, lives with her Swiss husband, Bruno - a banker - and their three young children, in a postcard-perfect suburb of Zurich.
Though she leads an affluent and comfortable life, she is falling apart inside. Adrift and increasingly unable to connect with Bruno, or even her own feelings, Anna tries to rouse herself with new experiences: German language classes, Jungian analysis, and a series of sexual affairs she enters with an ease that surprises her.
But she soon finds that she can't easily extract herself from these relationships. Having crossed a moral threshold, Anna will discover where a woman goes when there is no going back.
