Zhuge Zhengwo (played by Ma Dezhong), Yuan Shisanxian (played by Au Kam Tong) and Tian Yiju (played by Chan Kam Hung) are brothers in the same school. Among them, Tian Yiju knows that he can't make any achievements in martial arts, so he settles for the second best and begins to study Qimen Dunjia. Zhuge Zhengwo and Yuan Shisanxian are both talented martial artists. They are equally matched and are evenly matched opponents in the school. What makes Yuan Shisanxian regretful is that he has not been able to defeat Zhuge Zhengwo until he finishes his studies and goes down the mountain. Therefore, he is particularly persistent about this. After going down the mountain, Yuan Shisanxian chooses to live in seclusion in the mountains and forests to improve his martial arts, and regards Zhuge Zhengwo as his only opponent. Zhuge Zhengwo devotes himself to the court and serves the country. At the same time, a woman named Xiaojing (played by Charmaine Sheh) walks into their lives, which escalates the conflict between them again.
