During World War II, at the height of China’s war of resistance against Japan, a group of courageous citizens develops a top-secret underground espionage network right under the nose of the newly established puppet regime. At increasingly great peril to their own lives, the double-agents masterfully extract classified information from deep behind enemy lines, an effort that gives rise to the united front that will help turn the tide of the conflict.

This is the movie trailer for Hidden Blade, director Er Cheng's latest work starring Tony Leung and Wang-Yibo.
