At the turn of the century, a young Chinese girl escapes from a religious sacrifice, and is rescued by an honorable Tibetan herdsman. The two fall in love, but problems arise when she is ignorant of their time-honored traditions and runs into trouble with a glamorous and proud Tibetan princess.

Facing the country's enemy, the three set aside their disputes and jealousy, and join the militia force to protect their homeland.
