Su Wantang, the concubine of the prime minister's house, was framed by her aunt and forced to become the concubine of General Gu Chenzhou of Dingbei. She thought it was a profit transaction, but she was moved by misunderstandings and calculations one after another. Gu Chenzhou hates the Prime Minister deeply because of his family's old grudges. He will hide Su Wantang's tenderness as a sharp sword and repeatedly test her sincerity with neglect, humiliation and use. When Su Watang decided to leave in despair, a border war broke out. Gu Chenzhou knew that he had already fallen, but Su Watang lost his memory after blocking an arrow for him, which also implicated the secret connection between the murder of the Gu family and the Prime Minister's Mansion. The two redeemed each other in blood and fire, but they had to face the shackles of the identity of "killing relatives and enemies". Sadomasochism and rape were intertwined with murder. In the end, they exchanged their lives for lives to reveal the truth, and the ashes of defense were rekindled.
