During the Dongliang period, Ye Ningzhi, the pillar of the Hundred Opera Troupe, entered the palace with the troupe to perform for the Empress Dowager's birthday banquet. Unexpectedly, she was framed by the eldest princess. Fortunately, the first counselor Wei Guang rescued her. Ye Ningzhi has never forgotten Lord Wei since then. Half a year later, Ye Ningzhi unexpectedly entered the palace again and became a maid beside the queen. After witnessing all kinds of unjust, false and wrong cases, she relied on wisdom and courage to stand up for the bottom and show her sword to the powerful, becoming a clear stream in the harem, and even the most elusive queen was moved by her. The emperor who was high above was also attracted by Ye Ningzhi. Ye Ningzhi became besieged and difficult for a while. It turned out that the deep sisterly love was just a mirage, and Lang Kun, who seemed to be doing all kinds of evil around the queen, secretly provided help. At the same time, the eldest princess who had always coveted the throne made a comeback, and Ye Ningzhi was involved in a more treacherous power game. She and Wei Guang went deep into danger together to smash the conspiracy of the traitor and resolve the national crisis. Ye Ningzhi grew from a little maid beside the Queen to a virtuous concubine who shone in the darkness. In the end, she returned to the common people and gained the most sincere and regretless love.
