 Set along the southern coast of Vietnam during the French occupation in the 1940s, water is everywhere, giving life and bringing decay and rot. Kim is 15; his father and step-mother have two buffalo, their lifeline as subsistence rice farmers. During the rainy season, there s no grass and the buffalo are starving. Kim volunteers to take the beasts inland to find food. On this coming-of-age journey, Kim sees men mistreat women, men fight with men, and French taxes rob the poor. He works for Lap, a buffalo herder whose past is entangled with Kim s parents, and he makes friends who will lead him to his place in the world.
