Explore the buried clay warriors, chariots, and bronze weapons of China's first emperor.

In central China, a vast underground mausoleum conceals a life-size terracotta army of cavalry, infantry, horses, chariots, weapons, administrators, acrobats, and musicians, all built to serve China's first emperor, Qin Shi Huang Di, in the afterlife. Emperor's Ghost Army" explores how the Emperor directed the manufacture of the tens of thousands of bronze weapons carried by the clay soldiers. NOVA tests the power of these weapons with high-action experiments and reports on revolutionary 3D computer modeling techniques that are providing new insights into how the clay figures were made, revealing in the process the secrets of one of archaeology's greatest discoveries.
