Forbidden Arsenal

Forbidden Arsenal (地下兵工廠, 1991) is a Hong Kong action film you can watch online on iFILM. Officer Yeung can't close this case alone — a black-market weapons syndicate is manufacturing and distributing illegal arms at scale, and the investigation demands cooperation across borders. A Taiwanese officer and a Mainland Chinese colleague join her: three cops from rival jurisdictions who have to learn to trust one another before the trail goes cold.

Directors Yuen Jun-Man and Zheng Zhao-Qiang keep things tight at 87 minutes — shoot-outs, vehicle chases, and the friction of a joint operation where nobody fully trusts anyone else. Stream Forbidden Arsenal (1991) online on iFILM.
