Larry Buchanan, a world-renowned geologist, discovers an enormous deposit of silver beneath a remote Quechua village in Bolivia and unwittingly fulfills a 400-year-old prophecy that promised a life of wealth for the villagers. Karen Gans, a specialist in child development, is deeply disturbed by the prospect of displacing the people in order to open a mine. Thus begins the couple's life-changing journey into the Quechua community, their evolution from outsiders to trusted friends. Then part two of the ancient prophecy is disclosed to them, and they are shocked by the truth of its predictions: alienation, despair, even cannibalism.
