Ten years ago, the family of Shen Mengjun, the eight-year-old daughter of an official family, was hunted down, and her mother Meng Meiyun fought to save her. Shen Mengjun, who lost her memory due to serious injuries, was adopted by the genius doctor Shen Qianqiu and renamed Shen Tiaotiao. Ten years later, Shen Tiaotiao, who did not know her true identity, was coerced by Zhao Zerui, a cousin of the Lin family, to marry into the Lin family under the name of Shen Mengjun and became the wife of Lin Qinglan, the young master of the Lin family who became stupid due to poisoning. In her daily interactions with Lin Qinglan and his family, Shen Tiaotiao was moved by their sincerity and used the medical skills she learned to help Lin Qinglan find an antidote to restore him to normal. After that, the two joined hands to stop Zhao Zerui's plan to annex the Lin family's property, and also found Liu Zhongheng, the prefect of Yuzhou, who killed Shen Tiaotiao's parents. Liu Zhongheng, who learned that the matter was exposed, attempted to join forces with Zhao Zerui to deal with the Lin family. At the critical moment, Shen Tiaotiao and Lin Qinglan fought hard and exposed Liu Zhongheng's evil deeds to the court. In the end, the two successfully crushed the conspiracy of Liu Zhongheng and others, and the two lovers finally got married.
