The prince at the East Palace travels incognito and gets poisoned due to eating inappropriate food. Since the doctors in the royal hospital have no idea how to cure the poisoning, the top medical official, Doctor Long, asks Long Chongjiu to treat the prince. Liu Feichun, an imperial guard is assigned to investigate the case of assassination of the prince.

In the 1960s, Guo Xiaolu and Su Lingfang met for the first time. They should have grown up together because of an accident. The never-arriving letter allowed the two to embark on a different life trajectory and opened the fate of a lifetime. The reunion after a long absence coincided with the prosperity of the two. Ding Mengmeng (Li Tingting), Wang Xiaomo (Wang Xiaokun) and Wang Qingwei (Xu Weihao) were also accompanied by them. As the years passed, the fate of a generation was ups and downs in the torrent of the times. After Guo Xiaolu reunited with Su Lingfang after life and death, they made an unexpected choice.

When Liu Feichun serves as the police commissioner of Xiangyang County, a woman in the city is killed and her heart is stolen. Liu hurried to the crime scene and encounters Long Chongjiu who disguises himself as a roving doctor.
