Shen Yanqiu's tailor shop is located in the most inconspicuous alley in the French Concession, and she barely makes a living relying on her ancestral needlework. Cui Guilan asked her to pay protection money, Ding Muxian asked her to sell her ancestral craftsmanship, and even Huo Shenyan from the patrol room came to find trouble every day. Until that day when she was tailoring clothes for a lady, a three-second scene suddenly flashed before her eyes. That lady will die in the back alley of Paramount seven days later wearing the cheongsam she made. She thought she was struck by evil spirits, but she didn't know that this was just the beginning. A tailor's ruler can measure the length of a garment and the width of a sleeve, but it cannot measure the depth of a person's heart.
