Lin Shu, a genius restorer of cultural relics, lives under the huge aura and mystery of her late mentor, the legendary master. When a peerless ancient painting "Endless Picture of Mountains and Rivers" that was thought to have been burned appeared on the auction market, the entire art world was shocked. Everyone thought it was an authentic work, but Lin Shu relied on his innate "synesthesia" talent to discern its authenticity.
Shen Du, a top appraiser who is cold and rigorous and known as the "footprint of truth", was entrusted with authoritative appraisal of the painting. He believes in data and science, and scorns Lin Shu's statement that "paintings have heartbeats". The first encounter between the two was a fierce collision between intuition and rationality, and a sharp confrontation between artistic spirituality and scientific laws.
However, as the investigation deepened, an art crime conspiracy spanning many years gradually emerged. Underneath the forgery, there is actually the last clue left by his mentor. Lin Shu and Shen Du, old enemies with opposing stances, were forced to form the most dangerous alliance. They travel through the fog of truth and falsehood, wandering on the edge of desire and death. Not only do they have to uncover the shocking secrets behind the paintings, but they also have to face the complex emotions quietly growing in each other's hearts that cannot be measured by any yardstick. When the color of the truth finally emerges, can they depict each other's sincerity?
