Perfectly preserved 3000-year-old mummies have been unearthed in a remote Chinese desert. They have long, blonde hair and blue eyes, and don't appear to be the ancestors of the modern-day Chinese people. Who are these people and how did they end up in China's Takla Makan desert? NOVA takes a glimpse through a crack in the door of history, to a past that has never before been seen outside of China.
Seen in more than 100 countries, NOVA is the most watched science based television series in the world and the most watched documentary series on PBS. It is also one of television's most acclaimed series, having won many major television awards, most of them many times over.
