The plot is of the standard sort involving filial offspring who grow up trained in martial arts to avenge wrongdoing perpetrated against their parents. But in this case, there is a twist. Golden Horse winner Tang Ching plays swordsman Li Zhishan, head of a security escort service, who possesses the martial world’s most powerful weapon, the Golden Dragon Blade. However, his adulterous wife Yuexiang (Kao Pao-shu) conspires with her lover, a rival escort named Long Zhentian (Li Peng-fei), to kill Zhishan and steal his sword. Despite the villains’ best efforts, Zhishan still escapes, though sword-less, with his young daughter Xiaoyan and settles down with a swordsman-turned-herbalist (Ku Wen-chung) and his grandson Qingsong (Yueh Hua).
