Historical Chinese action feature from director Tian Zhuangzhuang.
Set in China's northwest provinces centuries ago, shepherd Lu Chenkang (Joe Odagiri) joins the ranks of General Zhang Anliang (Chung Hua Tou), whose forces are passing through the mountains.
Previously a placid, caring man, Lu's character quickly changes, until he becomes one of the General's most feared fighters, eventually assuming command when the General is sent home after becoming wounded in a barbarian attack.
As the winter closes in and Lu leads his men on the homeward journey, they take refuge in a mountain village, where Lu falls for local woman (Maggie Q).
With the troops about to continue on their way, the woman informs Lu that she belongs to a magical tribe that can transform themselves into wolves, and that as a result of their intimacy, he too now shares this ability.
