1930S, Jinling City. In order to investigate the murder of his family, Lin Mo, a genius in mental arithmetic, sneaked into Xiuyun Trading Company anonymously. In the labyrinth of numbers, she relied on her extraordinary wisdom to gain insight into the mysteries of the accounts, and searched for the same strange "scorpion tail" mark on her father's blood-stained clothes among the clues, but she did not know that she had already fallen into a bigger mystery.
Lu Jianshen, an underground worker disguised as a cynical reporter, was ordered to approach the mysterious new accountant. From temptation to appreciation, in the battle of wits and scheming, the two formed a life-or-death alliance in the crisis. At the same time, Ye Wanqing, the business owner and cheongsam beauty who is among the powerful, hides helplessness and struggle under the glory, and forms a female alliance with Lin Mo from games to sympathy in troubled times.
The gorgeous cheongsam is not only a symbol of the times, but also a deadly carrier for conveying information and hiding murderous intentions. The fate of the three people is intertwined, from secret fighting in the business world to the ups and downs of the espionage world, and they are jointly involved in a shocking conspiracy in the name of "Satin". In the overturned dangerous city, they must use wisdom and faith as blades to pierce through the many disguises and protect the dawn of their home and country under the bloody romance.
Intention: Hear the thunder in the silent place, and see the character under the beautiful scenery. The flame of personal revenge will eventually merge into the torrent of family and country justice, and women's wisdom and friendship are the sharpest and toughest blades to pierce the dark age.
