Hidden Blade

Set during the Second Sino-Japanese War, Hidden Blade follows underground operatives who put their lives at risk to gather intelligence and protect their country. After Japan's attack on Pearl Harbor, the Wang Jingwei regime declares war on Britain and the United States, shifting the balance of the conflict and opening the Pacific theater. As the situation changes, members of the Communist underground work to undermine relations between the collaborationist government and the Japanese occupiers. The film moves between action, drama, history and mystery, focusing on the dangerous, hidden work of agents operating under cover.

The cast is led by Tony Leung Chiu-wai as Mr. He, Wang Yibo as Mr. Ye, Zhou Xun as Ms. Chen, Wang Chuanjun as Captain Wang, Huang Lei as Mr. Zhang and Dong Chengpeng as Mr. Tang.
