ASIA-POL is in the process of trying to shut down a criminal organization that is smuggling large quantities of gold into Japan by refining it into phonograph components. Yang Ming Xuan (Wang Yu) succeeds in intercepting the latest truckload of contraband, but the criminals stage a brazen helicopter attack, ruthlessly eliminating their own operatives and destroying most of the shipment before it can be confiscated. In the process, Ming Xuan's partner is killed, and the young agent is brought to the unwelcome attention of the leader of the smuggling operation, a suave and psychotic operative known simply as George (Shishido Jo). Shortly after Ming Xuan's foiling of their latest smuggling attempt, George's gang assassinates a man known as Yang Zhang Qing, who is suspected of being the leader of the criminal organization's Hong Kong operation. Upon being informed of this by his superiors, Ming Xuan volunteers that he believes Yang Zhang Qing may be his real father and that, if so, could not have been a witting participant in the organization's criminal activity. After Ming Xuan is sent to Hong Kong to locate the gang's refining operation, he encounters a young woman, Ming Hua, who turns out to be a sister he never knew he had, and together the two set out to bring down George and clear their late father's name.
