Guan Hongmei, a modern tie-dye artist, accidentally traveled to the turbulent Shanghai in the late 1920s. When she woke up, she found herself next to the dying indigo vat of "Chen Ji Dye House". Faced with the desperate situation that the dye vat was "discolored" and the huge compensation was about to overwhelm the dye house, this Northeastern girl with a fierce personality used her chemical knowledge that transcended the times and her deep understanding of traditional colors to forcefully pull an "ancestral vat" back from the gate of hell with almost life-threatening ferocity. The "Tian Shui Bi" cheongsam that showed off her talent for the first time gave her her first taste of colorful clothes in Shanghai. She listed "Neon Clothes" to resurrect the lost traditional Chinese color spectrum - the noble "purple", the vibrant "pine flower yellow", and the poetic "moon white" - and endowed them with cultural souls. However, outside the alley, the business war is filled with smoke. Guan Hongmei did not fall. During the war, she used "cinnabar red" to ignite patriotic acts; under the blockade, she used traditional Chinese medicine residues to dye "isolated island green" that symbolizes the life of the isolated island, and used stove ash and rust to create "battlefield ash" that carries the memory of gunfire. When the shop was smashed and her mentor died to protect her craftsmanship, she hung the banner of "Unyielding Red" in the ruins and turned the dyehouse into a secret stronghold of resistance. She compiled "Colorful Colors of Colors", condensing her life's efforts and feelings for her family and country into a single square inch. At the darkest moment before dawn, she divided her forces and transferred the fire, completing the thrilling transmission of information with a "zhe yellow" dress. From the dyeing vat in the alley to the top original art palace in Shanghai, from the craftsman who pursues beauty to the guardian of cultural fire, Guan Hongmei uses a vat of indigo to tell how the Siberian tiger girl dyed her elegance in the foreign market ten miles away.
