This is the story of a pool and the animals that cannot live without it. It's a place where hippos and crocodiles survive in mysterious harmony. A crowded pool... where predator and prey are drawn together and where strange things happen that have rarely been seen before. At this pool thirst can be dangerous, and drinking... becomes a deadly game of chance. When the pool shrinks in an unrelenting drought... there is a desperate fight for life. A wild anarchy takes over that only the fittest can survive. Here in a strange communion hippos attend the last feast of the crocodiles. A river in Africa... It's known as the Luvuvhu or Hippo river, and where land and river meet there exists a rich concentration of animals. For countless years, this river has sustained life in the northern reaches of South Africa's Kruger National Park. When good rains have fallen there is abundant water for all, but this year little rain fell, the river dwindled to a narrow channel, and finally stopped flowing.
