Seems like an interesting combination of cultures. Here's the basic story from the film's Facebook page:
The 1860's, Chinese immigrants pan for gold up on Yellow Hill, but they have to contend with a corrupt Mayor and his gang of vicious lackeys. Enter The Stranger (Bai Ling), who is no longer accepted by her fellow immigrants but will fight to save them.
A homage to the films of Sergio Leone, but with a modern twist.
And some teaser images:
The premiere of Yellow Hill is set for early November.
