Hok, a crane-style Kung Fu master, is also a master at hiding. For the past 12 years, she has hidden the fact that she is a girl. Now her rogue brother, Ying, and his army have placed a huge price on her head. Fortunately, she manages to make it to Keifeng where she finds her mother and a "round-eye" with the very funny name of Charles. Together Hok and Charles start to make some sense of the magnitude of Ying's plans.
