It is a sequel to Yueh Feng's earlier Shaw Brothers' film, Rape of the Sword.

The story describes that Prince Wuyi abused his power to seize the Purple Light Sword, even killing Gan Daxiong and forcing Xu Mu to leave.

He also ordered his son Lu Tianxia to lead the evil family slaves to break into Gan's fortress, and to seize the sword by force in the name of mourning.

However, Xu Jin, Shengnan and others were injured in the battle, and Yanan, who was unharmed, went to Feihu Ridge to ask for reinforcements.

Xu Jin and Chaonan tried their best to protect the Purple Light Sword and escaped at the risk of their lives.
