With exclusive access to research conducted by University College London and the Terracotta Army Museum, this documentary uncovers new secrets of China's fabled warriors. The discovery of China's famous Terracotta Army in 1974 captured the imagination of the world. But that first dig only revealed a fraction of this enormous and extraordinary treasure. Since then, scientists have resumed work on the site, and their research has turned up a series of new discoveries about the warriors and the people who made them over two millennia ago.
