Lin Wan, an embroidery girl from Jiangnan, was selected into the palace embroidery workshop because of her unique skill of "double-sided embroidery" and became the most humble embroidery girl. She originally wanted to live a stable life, but because of her embroidery, she accidentally offended her beloved concubine and was falsely accused of "cursing the royal family". She was frozen to death in an abandoned courtyard in the depth of winter.
Before she died, the "Embroidery Needle" that had been with her for many years suddenly shimmered in her arms, bringing her back to the day she entered the palace. This time, she put away all her innocence, using the "hidden edge technique" of "double-sided embroidery" as a weapon, and past life memories as clues: she hid "auspicious patterns" in the dragon robe embroidery patterns, which caught the emperor's attention; she embroidered a "reminiscence handkerchief" for the fallen concubine Jing, which aroused the emperor's old love; she took the opportunity of repairing tributes to expose the corruption conspiracy of the embroidery workshop manager.
She walked step by step between the thread and the tip of the needle, not only to avoid the pressing steps of her beloved concubine, but also to find out the truth about her wasted death in her previous life; she unexpectedly met the fifth prince Xiao Yu, who was also excluded, and they used each other to trust each other. However, when she got close to the core of power, she discovered that every inch of the harem was soaked in the blood and tears of the people at the bottom. When the embroidery needle breaks through the layers of conspiracy, the embroidery girl who once struggled in the corner of the embroidery workshop will finally use silk thread as a blade to embroider her own way of survival in the cold night of the brocade tent.
