A fearsome swordswoman known as The Jade Raksha appears in the martial arts world and begins killing people whose surname is Yan. A swordsman figures out who she is, and asks her why – the answer being that a Yan killed her family 18 years ago… but she’s not sure exactly which Yan it was. He suggests that killing the innocent is wrong, but she only has vengeance on her mind and is not to be convinced.

In the twilight of the Ming Dynasty, the Imperial court is plagued by corruption as tyrants rule over the land. With the Manchurians preying on a weakened empire, war is imminent. To save the victims from their suffering, sorceress Jade Raksha fights the soldiers that oppress people for their own gain. As payback, local government officials decide to pin the murder of Governor Zhuo Zhonglian on Jade, turning her and the members of her cult into wanted fugitives for a crime they didn’t commit.
