Anna was a good wife, mostly . . .
Anna Benz lives in comfort and affluence with her husband and three young children in Dietlikon, a picture-perfect suburb of Zurich. Anna, an American expat, has chosen this life far from home; but, despite its tranquility and order, inside she is falling apart.
Feeling adrift and unable to connect with her husband or his family; with the fellow expatriates who try to befriend her; or even, increasingly, her own thoughts and emotions, Anna attempts to assert her agency in the only way that makes sense to her: by engaging in short-lived but intense sexual affairs.
But adultery, too, has its own morality, and when Anna finds herself crossing a line, she will set off a terrible chain of events that ends in unspeakable tragedy. As her life crashes down around her, Anna must then discover where one must go when there is no going back . . .
