1941, Shanghai Concession. Tailor shop apprentice Ye Kai was accidentally involved in a code-breaking mission, and he had to survive in the cracks of Japanese and puppet spies, military commanders, and underground parties. He didn't have a gun, just a pair of scissors and a photographic memory. Behind every tailor-made piece of clothing, there may be information about life and death hidden; every time a flying needle moves, a conspiracy may be sutured or torn apart.
