The Golden Sword Clan is under attack by the "Huainan Twin Evils". Fang Cheng, a servant of the clan leader Qi Rufeng, sacrifices himself to protect his master, dying together with the attackers. In gratitude, Qi Rufeng takes Fang Cheng's son, Fang Gang, as an apprentice. Although Fang Gang is highly regarded by his master, the other clan members despise him for his background. To avoid confrontation, Fang Gang leaves but runs into trouble with Qi Pei, his master's daughter. In the ensuing fight, Qi Pei cuts off Fang Gang's right arm. Fang Gang stumbles and falls off a bridge into the passing boat of Xiaoman, a peasant girl. Xiaoman nurses Fang Gang back to health and they fall in love. However, Fang Gang feels dejected as he can no longer practise swordsmanship due to his missing arm. Reluctantly, Xiaoman gives him a half-burnt martial arts manual and a broken sword which she inherited from her late parents. Regaining confidence in himself, Fang Gang practises the skills and masters a new, one-armed style of swordplay, making him stronger than before. Meanwhile, Qi Rufeng is planning to retire from the
jianghu and intends to name one of his apprentices as his successor. Around this time, his old foes – "Long-Armed Devil" and "Smiling Tiger" – seek to use the opportunity to destroy him so they ambush and kill his apprentices. When Fang Gang learns of the plot, he has no choice but to break his promise to Xiaoman to stay out of the
jianghu. En route, he defeats several enemies and shows up just in time to save Qi Rufeng. After a vicious battle, he manages to slay "Long-Armed Devil", and then turns down his master's offer to be the next leader of the Golden Sword Clan, choosing to lead a simple life with Xiaoman instead. == Cast ==
