In Suzhou City in 1932, 26-year-old Su Xiu was the heir to the century-old embroidery workshop "Jinxiu Hall". He worked on embroidery needles every day and took good care of his paralyzed mother. He believed that "steady stitches will lead to steady people's hearts" and only sought to live a stable life.
This stability was broken by Shen Wanshan, president of the Chamber of Commerce. This local snake who appeared to be charitable and coveted the embroidery workshop land. After Su Xiu refused to sell the house at a low price, he first cut off its raw materials and orders, and then sent his men to provoke him late at night. In the chaos, Su Xiu's mother was seriously injured, and Shen Wanshan bribed the doctor to stop taking the medicine, causing her death. Su Xiu came to the house to argue, but his right hand was broken, completely losing his embroidery career.
In despair, Su Xiu found a copper button engraved with "Shen Ji" in front of her mother's soul - this was the physical evidence left by her mother when she worked on Shen Wanshan's smuggling cargo ship in her early years. After encountering former arrest boss Zhou Hou, he learned that the copper buckle was related to Shen Wanshan's opium smuggling crime.
From then on, the embroiderer held the "blade". She asked her apprentice Achun to inquire about information, and followed Lao Zhou to learn to identify people's hearts, look for clues, and learn to keep accounts with her left hand. In the past, she only knew needlework, but she wanted to weave a net to catch sinners in the mist and rain of Suzhou. She only wanted Shen Wanshan to abide by the law, return justice to her mother, and let "Jinxiu Hall" remain innocent in the world.
