This film is adapted from the comic of the same name by Wong Yuk-lang. The brothers Wang Jianglong (Yuen Wah) and Wang Fuhu, who were born in a martial arts family, founded the Dragon and Tiger Gate to teach martial arts and uphold justice in order to protect the grassroots from oppression. Wang Xiaolong (Donnie Yen) and Wang Xiaohu (Tingfeng Xie) are a pair of half-brothers under Wang Fuhu's knees. When Xiaolong was a child, he was taken away from the Dragon and Tiger Gate by his mother, leaving a dragon-shaped jade pendant and a tiger-shaped jade pendant with Xiaohu. Xiaolong had a bad fate. After his mother died, he was adopted by the gang figure Ma Kun (Chen Kuan-tai). Xiaolong rescued the Rakshasa girl (Li Xiaoran) who later became a subordinate of the Fire Cloud Evil God and became the love of her life. As time flies, the young Wang Xiaohu and his fellow apprentices are involved in the dispute between Ma Kun and the White Lion Gang by mistake, and get the Rakshasa Order given to Ma Kun by the Fire Cloud Evil God. Wang Xiaolong retrieved the Luosha Order for Ma Kun, but he could not tolerate the despicable behavior of Ma Kun's men and fought with them. In the melee, Wang Xiaohu was helped by the martial arts-loving young man Shi Heilong (played by Shawn Yue). Wang Xiaohu met and got to know Ma Kun's daughter Ma Xiaoling (played by Dong Jie), and Shi Heilong also became Wang Jianglong's disciple as he wished. On the other hand, Ma Kun wanted to quit the world but angered the Fire Cloud Evil God. Wang Xiaolong fought hard and only saved Xiaoling. The Fire Cloud Evil God believed the delaying plan of the Luosha woman and swept through the Dragon and Tiger Gate alone. Wang Xiaohu and Shi Heilong were seriously injured. Xiaoling took the two to Baiyun Mountain for help. The Three Emperors of Dragon and Tiger practiced hard, preparing for the final battle with the Fire Cloud Evil God...
