Yueh Hua stars as an assassin who flees after killing a hated prime minister, with Lo Lieh as the relentless imperial guard who pursues him to a remote village being terrorized by bandits. When Yueh takes over the identity of a county officer newly assigned to the village, his ruse is assisted by a pretty innkeeper's daughter (Li Ching) who insists to Lieh that Yueh is indeed the county officer and happens also to be the cousin who was betrothed to her as a child. The confused innkeeper is persuaded by his daughter to support the ruse, thus delaying Lieh's efforts to arrest the wanted man.

Li Zhishan is a rich man, but wealth cannot keep the loyalties of his wife, who has been visiting the bed of a rival. She helps plot against him, and the Vicious Long Brothers invade his home and steal the Golden Dragon Blade - a sword that makes its wielder unbeatable. Zhishan, crippled in the attack, and his young daughter are whisked away by a devoted servant, and the trio soon find shelter in the home of an herbalist. Years pass, the daughter grows up to be a lovely young woman and a powerful fighter, and the Long Brothers use the Golden Dragon Blade to gain power in the region. Zhishan's family of sorts has managed to stay well hidden, but a trip into the city - the daughter's first - sets off an old power struggle as Zhishan's wife discovers her daughter is quite alive.
