Thousand Pieces of Gold.

In 1880s China, young Lalu is sold into marriage by her impoverished father. Rather than becoming a bride, Lalu ends up in an Idaho gold-mining town, the property of a saloon owner who renames her, China Polly, and plans to sell her as entertainment for the locals. Refusing to become a whore, Lalu ultimately finds her own way in this strange country filled with white demons.
