This drama is adapted from Jin Yong's martial arts novel "Flying Fox of Snow Mountain". After Li Zicheng's fall, his four guards - Hu, Miao, Fan and Tian - started a fight for treasures, which later evolved into generations of hatred among the four families. Hu Yidao (played by Felix Wong), a descendant of the Hu family, wanted to find the other three families to resolve the previous misunderstanding, but was secretly framed by Tian Guinong (played by Cheung Siu Fai), a descendant of the Tian family, and was mistakenly killed by Miao Renfeng (played by Wan Yangming), a descendant of the Miao family. His wife Lang Jianqiu (played by Maggie Shiu) was not spared either. Jianqiu entrusted her only son Hu Fei (played by Chan Kam Hung) to the care of the servant Ping Si (played by Liao Qizhi). When Hu Fei grew up, he wanted to avenge his parents and misunderstood Miao Renfeng as the culprit. When Ping Si took Hu Fei to track Miao Renfeng, he met Yao Yiyi (played by Liu Xiaotong) who was dressed as a man, and met the chivalrous woman Nie Sangqing (played by Teng Liming), but she had a crush on Chen Jialuo (played by Wei Junjie), the leader of the Red Flower Society. Later, Hu Fei met Miao Ruolan (played by Charmaine Sheh), the daughter of Miao Renfeng, but the rivers and lakes were dangerous, and several young people were deeply trapped in it with the grievances of the previous generation. Unlike other works adapted from "Snow Mountain Flying Fox", this drama does not involve too much content from "Legend of the Flying Fox", and even classic book characters such as Cheng Lingsu and Yuan Ziyi do not appear.
