This television documentary investigates the first people to come to North America. It begins with the discovery of a 9,000-year-old skeleton with a Stone Age weapon imbedded in its hip. The skeleton was found by Jim Chatters in Kennewick, WA, and dubbed "the Kennewick Man." Not only are there only a handful of skeletons this old found in North America, but this one is in excellent condition. Other skeletons and excavations reveal answers as well as new questions.
