In the Song Dynasty, the old emperor died suddenly, leaving behind a young prince. Regent Song Chen was entrusted by the late emperor to temporarily take charge of the government. He wanted to wait until the prince came of age to return to power and stabilize the Song Dynasty. Due to the pain of losing her husband and the desire for power, Concubine Yu kept brainwashing the young prince, causing the prince to regard Song Chen as his mortal enemy for the throne. Under Concubine Yu's instigation, he gathered forces everywhere in an attempt to bring down Song Chen.
