Fung Heng-Lit, the Mongol prince, lost his childhood memories during a massacre by Emperor Zhu. Heng-Lit escaped the massacre and grew up in China, where he becomes the chief of a clan. A Mongolian cult leader tries, by all means, to regain Heng-Lit's childhood memory and groom him into being a prince, hoping that Heng-Lit may lead the Mongol rebels in a campaign to overthrow the Ming Dynasty. However, Heng-Lit has his own dream, in which the Mongols and the Han Chinese live together in harmony.
