Police Story 4: Simple Mission Cantonese

This time, international police officer Chen Jiaju (Jackie Chan) was commissioned by the CIA to investigate an international nuclear weapons trafficking group. Both the boss and Jiaju thought it was a wild talk at first. They didn't believe that any organization could obtain nuclear weapons from the black market, and thought that what they were investigating was just a group of rabble-rousers. However, when Jiaju followed the suspect Xu Jie to conduct transactions and accidentally discovered the nuclear bomb base in Ukraine, he realized that the situation was serious. Both parties to the transaction discovered Jiaju, who lost his footing and fell into an icy lake while escaping. Fortunately, he survived after being rescued by the Russian army. After Jiaju recovered, Russian Colonel Grigg was sent to Australia to track down Xu Jie's sister Annie (played by Wu Chenjun). But as soon as Ka-kui arrived in Australia, he was hunted down by local gangs. Ka-kui had a vague feeling that there was something not simple behind the incident.
