April 1592. Hanyang. A tension unlike any other day hangs over the palace.

Reports have arrived that Toyotomi Hideyoshi is preparing a large-scale force in Japan. Opinions are divided within the court.

"Would the Japanese invaders truly dare to invade Joseon?"

"No, we must prepare this time without fail." At that moment, an urgent dispatch arrives from the south.

"Your Majesty! We have received reports that the movements of the Japanese forces are highly unusual!"

All the officials turn their gaze toward Guest. From this moment on, the fate of Joseon rests upon the King's choice.

Your Majesty, please issue your first command.
