King Lee Heon is feeling the walls close in on him as he can't seem to be able to trust anyone in court not to be out to kill him. In a moment of desperation he seeks the help of Lee Gyu, asking him to find a way for him to survive. Lee Gyu stumbles upon a clown named Ha Seon who looks just like Lee Heon. At the king's command, Ha Seon finds himself upon the throne while the real king seeks peace of mind at a secret location away from those out to kill him.
But while Ha Seon might look like the king, their personalities are different and Ha Seon soon finds it hard to not act upon what he sees as unfair.
