Xie Ning, the legitimate daughter of a general, disguised herself as a man since she was a child and supported the Xie family as a young general. Her father was jealous of the new emperor and committed suicide with regret, leaving only an order for her to save the family and her fifteen-year-old sister Xie Yao.
In the battle at the border, she made a surprise attack and defeated the enemy. Before receiving the reward, she received a secret order from the emperor and went to the miasmatic southern Guizhou to thoroughly investigate the poppy poison called "Beauty Face". Going deep into the wilderness of the southwest, clues point to the dark secrets of the new emperor's seizure of the throne.
On the way to investigate the case, she unexpectedly met and walked with the heir apparent of the Rong clan. The two admire and cherish each other, but due to the position of their family and country, each has their own bottom line and calculation. Undercurrents in the court, secret cases in southern Xinjiang, and checks and balances between the two countries are intertwined. While dismantling the chess game step by step, Xie Ning makes difficult choices between the honor and disgrace of his family, the morality of the monarch and his ministers, and the unspeakable fetters of confidants.
