Shen Tang, who was sold into the mountains for a large amount of money when he was young, hid in the mountains for ten years, returned with his certificate and stepped into the Lin family to seek revenge. The criminal memory of biological father Lin Yanqiu, which was sealed by drugs, gradually awakened in the face of physical evidence. The midwife, Granny Tian, handed over the contract before her death, and her last words were directed at the mistress behind the scenes, Zhou Yingxue; the former village chief, Chen Weidong, held a letter asking for help from the birth mother, and after being exposed by irrefutable evidence, the whole village was involved in the conspiracy. Zhou Yingxue repeatedly harmed Shen Tang in order to maintain his position, and his unique birthmark had already exposed his identity. Lin Zhixia, the youngest daughter of the Lin family, became suspicious of the old puppet with blood on it and turned to help secretly. Relying on the evidence collected over the years, Shen Tang gradually uncovered the old shady story of wealthy families using baby swaps to cover up infertility and buying and selling their own flesh and blood.
