On an ordinary day in June of 1964 in a small town in the Altiplano of Peru, Sister Mary Katherine (formerly known as Kate), a young American nun recently arrived in this very foreign place, walks away from her convent with no money and no destination.
Desperate and afraid of her feelings for an Irish priest with whom she has been working, she spends eight days on the run, encountering a variety of characters along the way: a cynical Englishman who helps her out; a suspicious Peruvian police officer who takes her in for questioning; and two American Peace Corps workers who befriend her.
As Kate traverses this dangerous physical journey through Peru, she also embarks upon an interior journey of self-discovery?one that leads her somewhere she never could have expected.
