The Legend of the Unknowns

HO and General GAY are the two leading and opposing mandarins when Ching EMPEROR HONG HAY is on the throne. HO has just returned from his mission to Korea, and the EMPEROR is happy about the fruitful outcomes. This further arouses the jealousy of General GAY, who is already anxious to get rid of HO. He grasps a golden chance to frame HO up. He informs the EMPEROR that HO has kept to himself a book named 'Book from Heaven', which is a guideline for governing the country. The EMPEROR is greatly annoyed and orders for the execution of HO and his family. HO's wife and only daughter FUNG are lucky to have escaped, but HO is captured. FUNG and her mother hide at the house of another mandarin, AN.

The house of AN is confiscated when the EMPEROR learns that he has helped the HO's. So his son LOONG, who is also the lover of FUNG, has to join FUNG as fugitives. MING, son of General GAY, falls for the beauty of the younger sister of the EMPEROR at the first sight. Immediately, he starts his courtship. But the young PRINCESS only shows her scorn. On the day when HO is to be executed, FUNG breaks into the execution ground to rescue her father. She kills thirteen royal guards, which has thus won her the name of 'GIRL THIRTEEN'; nevertheless, she still fails to get away with her father. She is fatally wounded. Luckily, the WONDER NUN arrives in time to save her from the spot.
