A look at the relics found in the tombs of China's Han Dynasty - an era that is generally considered the golden age of ancient China. It's up there with the Roman Empire in terms of international power at the time and has been a defining influence on the country's cultural identity ever since, with China's majority ethnic group referring to itself as the "Han people" and the Chinese scripts referred to as "Han characters". This programme examines how the emperors arranged to have their dead bodies mummified in the search for immortality and looks at a newly discovered version of the famous terracotta army - sculptures depicting the armies of Qin Shi Huang, the first Emperor of China.

It's clear the skulls are from Roman London, but nothing like this has been found before. This documentary unravels the mystery, using ground-breaking archaeological investigation. Who are these people and how did their skulls get there? There are many theories: they could be victims of a massacre, or gladiators; they could have naturally washed out of cemeteries in times of peace or be executed rebels; they could even be the victims of some grisly, long-lost ritual. Now the tools are available to solve the mystery. The investigation covers Boudicca's rebellion, the bloody gladiatorial arena, and head-hunting sites in France.
