Gil Chae is excited about the flower festival as she will be able to see Yeon Jun, her long-time crush. A stranger enters the village and interrupts the flower festival.

Gil Chae tries everything to draw Yeon Jun's attention but gets disappointed when she sees him with Eun Ae. Jang Hyun takes Gil Chae to places where noble women are not allowed. Jang Hyun plans to hold a 60th wedding anniversary for Grandpa Song Chu.

The Great Jin army intrudes on the borders, and the King has been captive at Namhan Fortress. They ask for the crown prince as hostage, and Yeon Jun and the scholars from Neunggun-ri volunteer to fight for the country.

Jang Hyun hears the horses and realises the intruders are near the village. When Gil Chae and Eun Ae are about to cross the river to flee from their village, the intruders arrive at Neunggun-ri.

Even though Gil Chae tries to deny her feelings for Jang Hyun, she is worried about him joining the army. Yeon Jun gets stabbed by the enemy, and Khan is on his way to invade Joseon.

Jang Hyun and Ryang Eum disguise themselves as intruders to sneak into their troops and meet Khan. The King of Joseon wants to make peace with them before they bring further disaster. Khan proceeds to conquer Ganghwa Island.
