Yue Xihong (played by Gu Feng) is the evil leader of the Iron Boat Gang, commanding the infamous Thirteen Eagles as his henchmen to eliminate his enemies. Sima Xin (played by Yang Zhiqing) is a highly respected figure in the martial arts world; being upright, he naturally becomes a thorn in Yue Xihong's side, ultimately leading to the demise of Sima Xin and his family at the hands of the Thirteen Eagles. Qie Mingxing (played by Di Long) is a member of the Thirteen Eagles, who, despite still holding onto some goodwill, can no longer tolerate Yue Xihong's wanton killings of innocents, thus he leaves the gang. Yue Xihong regards him as a traitor and orders his men to hunt him down. During his escape, Qie Mingxing saves a young man, who is actually Zhuo Yifan (played by Fu Sheng), Sima Xin's son-in-law. The two valiant heroes quickly find common ground and not only annihilate the assassins sent to kill them but also return to Yue Xihong's base with a vow to rid the martial arts world of evil.
