Deputy Minister Kang successfully deceives the Emperor of Khitan and returns to Gaegyeong to relay the news to Hyeonjong. However, the chancellors are not pleased as they believe he took the chance to negotiate with the Khitans. Meanwhile, Gwakju, Yeongju, and Sukju have fallen, and the Khitan army is on their way to seize the Seogyeong Fortress.

Despite Kang Gam Chan's plea, Wang Sun stands firm, refusing to abandon the fortress and his people.

Alone in Gaegyeong, Kang Gam Chan makes the fateful decision to buy precious time for Wang Sun's escape.
