Female doctor Jiang Xinyi was falsely accused of poisoning more than a hundred mountain bandits and stealing government money for disaster relief. She was escorted to Dali Temple in Beijing to await trial. Li Feibai, who happened to be on his way to serve as the Shaoqing of Dali Temple, passed by the inn. He trusted Jiang Xinyi's medical skills, and the two of them went to the epidemic area together. Li Feibai was captured by the county magistrate and revealed his identity, and finally gained the trust of the people. Jiang Xinyi's prescription was promoted, and her own unjust case awaited a thorough investigation by Dali Temple.
