1937, Peking. A former Northeastern Army special forces member was silent. After retiring due to injury, he was dawdling in the police station. He is poor-talking and lazy, but he solves crimes like a god. As the Japanese troops approached the city, a series of strange murder cases broke out one after another - massacres in military camps, curses on ancient tombs, and mysterious disappearances. Silence discovered that all cases pointed to the same secret. The enemy is around him, and war and suspense are intertwined. He must find out the ghost hiding in the shadows before the gun fires.
