Modern military doctor Su Qiaoxue worked undercover in the D-country drug trafficking group. When the mission was about to be completed, his identity was exposed and he was brutally tortured to death. When she opened her eyes again, she was dressed as Xie Zhenyue, the legitimate daughter of the Xie family in Daning - a concubine who had just been married to Prince Jingning by the Queen Mother, but was thrown into the dungeon for "poisoning the prince".
Trapped in the palace's confusion, facing chains and interrogation, Su Qiaoxue relied on the calmness and wisdom of a military doctor to prove herself: with her medical skills, she transformed from "everyone shouting for beatings" to the person most trusted by King Jingning Chen Wang.
Chen Wan was burdened with the fate of "defying his father and his mother" and was forced to station in the North Army camp for fifteen years. He earned the reputation of "God of War" with his military exploits. After the death of the late emperor, he returned to Beijing to assist in the government. Seeing that the government was controlled by the queen mother, he transformed into the cold-faced King of Hell to protect the young emperor, but was tricked by someone close to him into marrying Xie Zhenyue. While getting along, he discovered that Su Qiaoxue actually overlapped with the girl who saved him on a snowy night when he was a child and had a plum blossom birthmark on her arm - that was a thought he had hidden for fifteen years.
When the two teamed up to break the situation, uncover the truth about the death of Xie Zhenyue's mother, and unravel the Queen Mother's conspiracy, the war in the North broke out. During the war, she saved lives and healed the wounded with her medical skills, and he guarded the territory with courage, and his love was sealed in the righteousness of his family and country.
Su Qiaoxue suddenly refused to be a substitute, and Chen Wan also had deep feelings for her living in front of him. They finally uncovered the mystery of their life experience and conspiracy, and on their journey to protect the country, they completed the two-way redemption of country and love.
Purpose: Redemption of love, choice between country and family
