PLOT
There is no power struggle that is more cruel and vicious as among the concubines in a royal palace.
Jo So Yong is a beautiful but conniving royal concubine during the Joseon Dynasty who will stop at nothing to win the love and power of King In Jo. Although she is from the lower class, she uses her unparalleled beauty and wit to gain power and control over Joseon, even if it means getting rid of Crown Prince So Hyun so her son can be king.
When Lady Jo finally gets the power she wanted, it results in the bloodiest battle.
