The Ji family of Yizhou produces the coveted "Shu Red Silk," a treasure so rare it earned the saying, "In front of Shu Red, all other reds lose color."
Ji Ying Ying (Tan Song Yun), the young daughter of the Ji family, was gifted with intelligence and a passion for silk dyeing. Her talents gradually began to shine.
Yang Jing Lan (Zheng Ye Cheng), the son of the prestigious Yang family, returns after years of studying abroad, bearing the title of Jin Guan (Brocade Officer). Though dismissed as a "short-lived official" in a token position, this seemingly frivolous young master lies low, maneuvering carefully to uncover the truth behind an unsolved mystery from years ago.
Meanwhile, Ji Ying Ying's exceptional dyeing techniques earn her widespread fame in Shu, drawing the attention of Cheng Feng Ze, the White King of Nanzhao, who has long coveted the secret methods of the local brocade families.
As Nanzhao's encroachment intensifies, Yizhou faces turbulent times. Ji Ying Ying courageously steps forward, risking her life to protect the artisans under her care. Meanwhile, Yang Jing Lan ventures into Nanzhao, joining forces with Ying Ying to negotiate with their enemy. Together, they revive the brocade industry and leave behind a legendary tale of Shu brocade.
