In the hamlet of Zhelai Zhai in rural China, the rusty yellow hair and Caucasian features of some of the villagers have for centuries intrigued their neighbours, historians and not the least, the villagers themselves. For within their looks lies a mysterious heritage.

Appearing in an historical atlas of China under the ancient Chinese name for Rome, this small village may well have been a Roman city, populated and defended by Roman legionnaires. 

Following the recent recovery of artefacts from the village, as well as DNA testing proving genetic links between Europeans and the villagers, this fascinating documentary reveals a crucial missing link in our understanding of the world.
