In a world ravaged by war, the four great nations, Jin, Yan, Liang and Qin, are ceaseless in their pursuit of power and ultimate domination. In the midst of this endless conflict, the nations of Jin and Yan clash, and the great house of Jin falls. Forced to flee, the Jin prince, He Xia (Sun Yi Zhou), and his brilliant military strategist, Bai Ping Ting (Angelababy) escape death. But fate is not on their side.
Separated during their exodus, He Xia makes his way to the Kingdom of Bai Lan to pursue revenge against the Kingdom of Jin. Meanwhile Bai Ping Ting finds herself at the mercy of Chu Bei Jie (Wallace Chung), the Jin army’s greatest general and the nation’s most beloved prince. Immediately recognized by the prince, as the girl he fell in love with years ago, Bai Ping Ting soon finds herself the object of her greatest enemy’s desire.
Eventually recognizing Chu Bei Jie as the boy she once loved, Bai Ping Ting gives into the desires of her heart, setting into motion a complicated romance that pits the desires of the heart against the loyalties both have for their kingdoms.
