In the winter of 1939, Shanghai fell. Lin Mobai makes a living repairing watches at the Xiangtai Watch Shop on Xiafei Road, but he monitors the entire street with his eyes at night - night vision heat senses, penetrating the walls, and the human body is like a moving furnace. The price is migraines and brief blindness under the searchlights. By chance, he intercepted an encrypted telegram from the Japanese Army's Special Intelligence Laboratory and discovered a large-scale raiding plan against Nanjing. It must be deciphered and transmitted within four hours, otherwise the password will be changed and everything will be invalid. Lin Mobai resumed his old career, but attracted the attention of all parties: the military commander wanted to lure him back to the team, the underground party wanted to win over him, No. 76 Wanted to get rid of him, and the special high school wanted to use him. During a night vision assassination, his ability was discovered by Masao Yamamoto, the head of the Japanese Special High School Course, and a hunt for "night vision ghosts" was launched. Lin Mobai must use codes and bullets to fight his way out of the cracks between the country, the Communist Party, Japan, and the puppets. And what is the true identity of Su Jing who has always protected him? When the battlefield intersects with espionage, every assassination is a gamble with your life.
