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.
