When a Western Han lacquer cosmetic case is unearthed at an archaeological site in Jiangdong City, folk restorer Shen Huaijin is called in to take charge in the crisis, fighting side by side with young researcher Jiang Wanyin. Inside the case lie a bronze mirror, a bone comb, and silk manuscripts that reveal the dying words of a woman named A Heng from Guangling. An antiquities dealer, Zhou Huaimin, comes calling under the pretext of restoration, but in truth he covets the excavated treasures. Shen Huaijin secretly makes a replica implanted with a tracking marker to lure the snake from its hole. After the replica is stolen, its coordinates are exposed, and law enforcement officers catch the thieves on the spot. The genuine lacquer case is safely installed in the museum. When the autumn exhibition opens, A Heng's story, spanning two thousand one hundred years, warms countless visitors. The ancient ink studio and the Huaiyuan Hall pass the torch from generation to generation, and the road of cultural relic protection never ends.
