Zhong Yi, a cultural relic restorer, guards the national treasure day and night, but witnesses the theft of a bronze and gold statue. He confronts Gu Huaizhi, the president of the auction house, for the first time at the auction. One sees through fakes with his professional vision, and the other hides secrets and acquiesces to the transaction. The two confront each other tit for tat in the field of cultural relic appraisal.
In order to recover the national treasure, their superiors assigned a secret mission, and Zhong Yi and Gu Huaizhi were forced to pretend to be a collector couple and sneak into the black market. She didn't know that he had another certificate of authenticity hidden in his pocket, nor did she know that his true identity was related to the National Security Bureau. As the investigation deepened, the two discovered that behind the smuggling of cultural relics was a transnational money laundering network and family secrets that had been dusted for decades.
At the thrilling climax of the auction, Gu Huaizhi held up his hand and bought the fake necklace Zhong Yi was wearing - a key prop to reveal the final truth. When the mission of cultural relic protection is intertwined with secret emotions, can they break through the many traps, return the national treasures lost overseas to their homeland, and allow the two hearts to truly get closer in the process of protection?
