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.
