Underground Arsenal

Policewoman Yang Jingjing cooperates with undercover police officer Cheng Aoqun and China police officer Hua Zhiyong to arrest Hong Kong gang members in China's underground arsenal. Edna, the sister of Paul, the leader of the gang, does not agree with her brother's actions. Ben, Paul's gang leader, is interested in Edna. Unexpectedly, Edna falls in love with Lian Yong wholeheartedly. Due to the different backgrounds of Aoqun and Zhiyong, the two often clashed. Aoqun was a romantic, but secretly fell in love with Jingjing. Paul bought a large number of firearms from the leader of the Chinese arsenal and at the same time sent people to rob in Wan Chai to distract the police. Zhiyong and Ben compete for Edna's heart, but after the relationship between Edna and Paul is exposed, Paul puts Edna under house arrest. Edna attempts to call the police and persuade Paul to surrender. Unfortunately, Paul is trapped in the trap and eventually dies from Aoqun's gun, and Aoqun also wins Fangfang's heart.
