The film is set in the early 20th century. Wong Fei-hung, along with his romantic interest 13th Aunt and apprentice Clubfoot, travels from China to America to visit another of his apprentices, "Bucktooth" So, who has recently opened a branch of Po-chi-lam, Wong's traditional Chinese medicine clinic, in San Francisco. While travelling by carriage across the wilderness, they pick up a friendly cowboy, Billy, who is almost dying of thirst. When the party stops to have lunch, a bunch of hostile Native Americans ambush them. Although Wong, 13th Aunt and Clubfoot escape unharmed, their carriage is destroyed. 13th Aunt and Clubfoot are rescued and taken to "Bucktooth" So's clinic. Wong, however, hits his head on a rock and loses his memory as a consequence. He is saved by another Native American tribe.
In San Francisco, Billy tries to stop the corrupt mayor from imposing discriminatory laws to make life difficult for the Chinese migrants. Meanwhile, the Native American tribe that saved Wong gets into trouble with a more powerful rival tribe. The chief's son, Fierce Eagle, is injured by the rival tribe's leader. To everyone's surprise, Wong defeats the rival tribe's leader and half of his men, causing the rival tribe to flee in fear. He eventually makes his way to San Francisco and regains his memory with the help of his companions, but forgets everything that happened during his bout of amnesia.
In the meantime, the mayor has fallen into debt so he hires a Mexican bandit to help him rob the bank and frames the people in Po-chi-lam for the robbery while he secretly plans to abscond with the loot. Wong and his companions are arrested and sentenced to death by hanging. Just then, the Mexican bandit discovers that the mayor has paid him less than he expects so he returns to claim his money, thus revealing the truth. In the ensuing fight, the mayor is killed and Wong manages to capture the bandit and clear Po-chi-lam's name. At the end of the film, Billy is elected as the new mayor while Wong, 13th Aunt and Clubfoot return to China.
Jet Li's return to the series opened on the weekend of Chinese New Year, and faced stiff competition from director Hung's own film, Mr. Nice Guy. Still, it grossed HK$30,268,415 at the Hong Kong box office.[1]
Mandarin version
A sync-sound Mandarin soundtrack features a number of the Chinese actors speaking their own language (including Jet Li, Patrick Lung - Richard Ng speaks Cantonese however), whilst others are dubbed.
