Hapkido (Chinese: 合氣道), released as Lady Kung Fu in North America, is a 1972 Hong Kong martial arts film directed by Huang Feng and starring Angela Mao.
Yu Ying, Kao Chang and Fan Wei are sitting and talking in a park when they are approached by a group of Japanese toughs.
The Japanese, who consider it an inferior martial art, try to run them out of town with some traitorous Chinese, including Chou Ba-tien.
Yu Ying, Kao Chang and Fan Wei do not want any trouble as it goes against the wishes of their master and his teachings.
This does not go down well and Fan Wei becomes a wanted man, having to hide out while Yu Ying and Kao Chang try to reason with The Black Bear Gang without much luck.
