Living a torturous life of poverty and barely able to survive, Hwa-yeon decides to offer herself as one of the king’s concubines. Once inside the royal palace, two men are immediately seized by the woman - the Grand Prince Seong-won, a megalomaniacal ruler drunk with power and lust, and Kwon-yoo, who has everything to lose if his desire for Hwa-yeon is exposed.
