"Iron Vest" Yim, and decides to follow him. Yim wants to become famous and start a martial arts school in Foshan, but he needs to prove himself first. One night, the Shaho Gang sets fire to Po-chi-lam in revenge, after which they flee and take shelter under Jackson, an American official. In return for protection from the authorities, the Shaho Gang helps Jackson run his underground human trafficking ring by kidnapping Chinese women to be sent to America as prostitutes. When Wong and the Governor are watching an opera performance, the Shaho Gang and Jackson's men ambush them and try to assassinate the Governor and kill Wong. Their plan fails but many innocent people at the theatre are wounded. The Governor blames Wong and threatens to arrest and execute him, but allows him to give medical attention to the injured. While tending to the injured people in his clinic, Wong meets an escaped Chinese labourer from America who relates his story of how he and his fellow labourers were treated in America. Just then, Yim arrives at Po-chi-lam and insists on challenging Wong to a fight to prove he is the better fighter. Yim leaves with Leung Foon, who was fired from the opera troupe, after he was defeated by Wong but later joins the Shaho Gang instead – even though Leung strongly objects to Yim working with the gang. Shortly after Yim left, the Governor shows up and orders his men to search Po-chi-lam for fugitives. Wong and his apprentices fight with the Governor's men until 13th Aunt, "Bucktooth" So and the labourer have escaped. Wong then surrenders himself and is imprisoned along with his apprentices. In the meantime, the Shaho Gang kills the labourer, abducts 13th Aunt and takes her to their base. "Bucktooth" So escapes and goes to the prison to inform Wong. The prison guards release Wong and his apprentices out of respect for him. Wong and his apprentices disguise themselves and infiltrate Jackson's base to find and rescue 13th Aunt. Yim engages Wong in a one-on-one fight and again, Wong defeats Yim for the second time in a row, and realises that he has been cheating in fights; there is a small spearhead tied onto the tip of Yim's queue (which Wong uses to tear Yim's queue in retaliation for cheating) at the same time, Wong's apprentices and Leung Foon overcome the Shaho Gang and
