1942, Shanghai. An unknown apprentice in a tailor shop is actually "Nighthawk", the highest-level hidden agent of the military. He used needles and threads as weapons, abacus as intelligence, and played spy wars under the eyes of the Japanese and puppets. While his colleagues were still guessing whether he was a traitor or a hero, he had already used the enemy's secrets as cloth and stitched them into a pattern of victory stitch by stitch.
