Felix Chacaltana Saldivar is a hapless, by-the-book prosecutor living in a small town, six-hundred kilometers from Lima. Until now he has led a life in which nothing exceptionally good or bad has ever happened to him.

As he investigates he must confront what happens to a man, and to a society, when death becomes the only certainty.
