When 600,000 costumes were smashed and the top actor Gu Heng was furious, wild painter Su Yao came to the rescue with her ancient paint restoration skills and was tied to the "Dunhuang Long Song" project with a sky-high price contract.
She is a dropout from the Academy of Fine Arts, and he is a top-notch capital controller. The two of them should be completely different, but their hearts palpitate at the same time in front of the fragments of Dunhuang - she saw the Tang Dynasty painter A Yao throwing himself on the fire to protect the murals, and he dreamed of General Xuanlang weeping blood on the battlefield, and his thousand-year fate followed him like a shadow.
The Qi family set up a bureau to monopolize the raw materials, Gu's father and mother forced each other to prevent them from exploring Xuanlang Cave, and there were even weird legends about "it" awakening that entangled the two of them. From the suspicion between employees, to the protection of each other in a sandstorm, from the unfinished secrets of their mother's generation, to the flying symbol deep in the cave, in the sand of Dunhuang, what they solved was a thousand-year mystery, and a renewed love that spanned time and space.
