In San Francisco, Billy tries to stop the corrupt mayor from imposing discriminatory laws to make life difficult for the Chinese migrants.

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.

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.

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.
