In the 9th year of Wude Period of Tang Dynasty, Li Changge, the daughter of the former crown prince, accidentally escaped from the military coup in the palace. During her escape, Changge encountered the secret service agent of a grassland tribe, Ashina Sun, who was under the pseudonym of Qin Zhun. They got to know each other through a fight and their affection grew stronger. Changge smashed a conspiracy in Youzhou. However, at the same time, her identity was revealed, and she went to Shuozhou to escape capture. She hid herself beside Gongsun Heng, the governor of Shuozhou, to help him resist the invasion of the grassland forces, but she did not expect that the enemy general was Qin Zhun. Changge was shocked and distressed to discover Qin’s real identity. However, the situation in Yuzhou is in great danger. In order to gain time for reinforcements, Li Changge negotiated with Sun. For the sake of the overall situation, she was willing to be a prisoner and taken to the grassland. Then she accidentally learned that the Great Khan had an ulterior motive. Changge decided to temporarily put aside her personal vengeance, and risk her life to save the situation. In order to save Changge, Sun disobeyed the order of the Great Khan, but they were far apart from each other after that. After going through the arduous exile, Changge gradually understood the principle of the invincibility of the benevolent, and finally put aside her personal grievances. After discovering that the former forces of Sui Dynasty were the manipulators behind the scenes, Changge and Sun teamed up to protect the peace of Tang Dynasty and the grassland. They finally came to realize their deep affections towards each other and went to confront the crisis ahead.
