Anxious about the traitors out there and haunted by the ghost of the brother he killed, Heon can never sleep in peace. He desperately asks the Chief Royal Secretary, Lee Kyu, to find a way to eliminate his fears. Like what the Monkey’s hair does in “Journey to the West”, a doppelganger of Heon appears before his eyes

As soon as Heon sees Ha Seon, he leaves the palace right away. Eunuch Cho and Lee Kyu try to train Ha Seon to perform a perfect double of the King. Ha Seon gradually realizes that he is needed in the palace to die instead of the king. To frightened Ha Seon, Kyu advises the ways to survive in the palace.
