As power struggles have arisen throughout Ancient China, a deadly struggle begins to emerge from the King's own seraglio. In order to gain the terrifying King Xun's favor, Ninghu's family is determined to make her the future Queen, despite King Xun's disinterest in concubines.
Ninghu agrees to her brother, Yuanren's plan to disguise herself as an eunuch servant to her brother in order to get close to the King. However, the plan is risky and dangerous. It becomes even more risky as Ninghu becomes infatuated with the King's most trusted advisor and eunuch, Lingyu who suspects Ninghu's true gender.
The relationship between the king and Lingyu is intriguing and arouses jealousy. But it is nothing compared to the mess that will occur when the two men will be interested in Ninghu.
