In the winter of 1944, the beach in Shanghai was in turmoil. Chen Mo, deputy director of the Operations Division of the Wang Puppet Secret Service Committee, appears to be a ruthless "traitor eagle dog", but in fact he is an underground member of the Chinese Communist Party code-named "Pendulum Bell".
In the darkest hour before dawn, a top-secret file "Project Ashes" related to the post-war situation appeared, and Chen Mo must safely transfer it within 48 hours. However, Gu Weizhou, the new station chief of the Military Reunion Shanghai Station, parachuted into the special committee. This man has a keen sense of smell and acts crazy, and he quickly focused his suspicious eyes on Chen Mo.
After a seemingly ordinary interrogation and execution, the only token used by Chen Mo to hand over intelligence to his superiors - a pocket watch with microfilm hidden in it - mysteriously appeared on the body and fell into the hands of Gu Weizhou. Although Chen Mo temporarily resolved the identity crisis with his quick wit, the intelligence handover point was suddenly intercepted by a third party, and the token was completely missing.
Facing Gu Weizhou's pressing psychological temptation and the possible "third eye" inside, Chen Mo was forced to fight alone in the cracks of many forces. He must use misplaced information and human weakness to retrieve the lost token under the eyes of the enemy, and complete a life-and-death breakout involving faith in this silent secret room game.
