During the rainy season in Shanghai, antique broker Lin Zhixia went toe-to-toe with the new financial upstart Shen Yanci at Sotheby's spring auction for a Yuan Datou signed in the third year of the Republic of China. This auction unexpectedly revealed a mystery that had been buried between the two parents for twenty years - the ancient coin that Shen Yanci's mother entrusted Lin Zhixia's father to identify was authentic and was mistakenly judged to be a fake, causing the fate of the two families to take a turn for the worse. With in-depth investigation, they discovered that there was a shocking conspiracy behind the mistake in the identification of ancient coins. The person in charge of Sotheby's colluded with the antique dealer Uncle Zhou to set up a trap. In the process of pursuing the truth, the two not only solved the family knot, but also found each other's emotional destination in the gilded years of ancient coins.
