The film is set in the final years of the Qing dynasty. A Triad (underground society) boss known as "Jade Faced Tiger" collaborates with foreigners to take over a town and exploit the residents. That night, while Tiger is watching a Chinese opera performance, the actors on stage suddenly attack him. The lead actor is "Iron Monkey", a masked fighter who helps the poor and punishes the wicked. Tiger narrowly survives the attack when his henchmen show up and drive away Iron Monkey.
