Shen Yulou, a modern pediatrician, is accidentally injured by his girlfriend and falls into coma, and travels back to the body of a death row prisoner from the Dahui Dynasty. It happened that the imperial concubine was seriously ill after giving birth, so he entered the palace for treatment because he did not want to get involved in the harem battle between the empress and the imperial concubine. With his professional medical skills, he detoxified the poison, rescued the princess, found out the truth behind the murder of the prince, and solved many murderous situations. However, he did not expect that the biggest murderer behind the scenes turned out to be the person closest to the emperor.
