Crown Prince Bongrim (Lee Min Ho) starts to manage the affairs of state for King Injo (Kim Jae Won) who is in a lot of pain. The King asks his son to be a better king whatever he does.
After reading Seungjeongwon Ilgi (the Diaries of the Royal Secretariat) about two Manchu invasions, Bongrim makes an example of a senior government official.
Meanwhile, Princess Jeongmyeong (Lee Yeon Hee), feeling a threat to her own safety, prepares for last fight.
The new Crown Prince and Hong Joo Won (Seo Kang Joon) are first to hold out the olive branch to Kim Ja Jeom (Jo Min Ki) and Kang Joo Sun (Jo Sung Ha).
By all appearances, the two powerful figures in politics seems to have same opinions.
As a mysterious box is found in living quarters of Jo Yeo Jung (Kim Min Seo)'s son, Kim Ja Jeom is in danger due to conspiracy against the Bongrim. He is completely at a loss when the dirty work begins to take an unintended turn.
Just then, the big merchant tastes the joy of victory.
Constant slandering and scheming and betrayal.
It's really splendid politics. Don't you think?
