This documentary is also a detective story spanning three decades, a search that lead to the rediscovery of remarkable archival footage in musty old film vaults, and their digital equivalents. The first half of the 20th Century in China saw the collapse of Imperial rule, the rise of so-called Warlords, the onset of the Chinese Civil War, invasion, and occupation by Japanese military forces, followed by a renewed Civil War between the Nationalist and Communist parties, leading to revolution. And it all happened in less than 50 years. Today America and China have deep, fundamental differences. In fact, it’s no exaggeration to say relations are terrible and threaten to get even worse. How did we reach this point? The answer to that question can, in part, be found in historic film footage, much of which was lost, stolen or at the very least misplaced for decades.
