In the thirty-seventh year of Yong'an, the 372 members of the Su family, the general who ruled the country, were massacred by the regent Shen Yuzhou on the charge of collaborating with the enemy and treason. Only the legitimate daughter Su Wan was imprisoned in the cold courtyard of the Regent's Palace and was barely surviving. She was once the most beautiful daughter of a general in the capital, well versed in military science and skilled in poison medicine, but now she has become a prisoner. The scar on her neck and the bloody tiger talisman fragments are her only obsession to support her survival. Shen Yuzhou is her enemy and the boy whom her father saved ten years ago. He used the most ruthless means to destroy the Su family, but he stopped outside the cold hospital late at night; he forced her to drink the drug of forgetfulness, but secretly sent a doctor to save her when she was dying. When Su Wan escaped from prison and united with the old Su family members and loyal courtiers to uncover the truth step by step, he discovered that behind Beidi's collaboration with the enemy, there was a conspiracy to subvert the dynasty. As a woman, she carried the banner of revenge, and passed away in the treacherous court and the smoke of the battlefield. In the end, she killed her enemy and avenged her injustice, but at the peak of her power, she understood the weight of love, hate, and family and country.
