An African-American ex-con saves the life of a white professor on a subway platform in New York City, even though the professor didn't wish for such deliverance. The incident leads the two men back to a Harlem apartment where hope and despair clash in a battle that shakes both men to the core of their existence. Is one an angel? Is the other completely lost? Pulitzer Prize-winning novelist McCarthy's fierce and passionate writing explodes in this drama of two lives changed forever by an act of grace.
