During the reign of King Yeongjo in the Joseon Dynasty (1302-1910), the villainous retainer party led by Jang Ji-hang gains power after cutting the head off a royalist Hong seong-won. His son Hong Guk-yeong passes a state exam and tries to assist the king in ruling well, but he is also put to death by Jang's false incrimination. But he is called a faithful politician in history.

Inspired by Shakespeare's classic of the same name. Beautiful and rich, Yeon-su (Park Jung-a) lives a life of freedom and indulgence, having any man she wants. That is, until she meets and falls for her polar opposite in Jung-do, an awkward and polite young gentleman. Meeting her future in-laws is a baptism by fire as she learns to become a proper lady. Little does she know that the family is actually the head of a notorious mob, setting up a blood feud.
