The Australian police was tipped off about a drug deal at Ayers Rock and managed to arrest a Chinese drug dealer Wen Zhan (played by Sammo Hung in a cameo role). When Wen refused to talk, the Australian police sought the help of Inspector Fang Shing Ling (Jimmy Wang) from Hong Kong Special Branch and arranged for Wen's extradition.
When Wen finally broke down during Fang's interrogation, he fingered a local business tycoon, Wilton as the man behind the criminal activities. When Wen was gunned down on his way to court, Fang went after Wilton. He traced Wilton's connections to a martial arts center where he was ambushed and wounded. Will Fang put Wilton behind bars?
