Two childhood sweethearts vow to marry one another after they are separated by war.
Jin-ha and Sullie (Hyeon-jun Shin and Hee-seon Kim) are childhood friends in 12th century China. When Sullie's mother dies, her father relocates to a different city, but both vow never to marry until they meet again.
While Sullie is gone, Jin-ha masters a secret form of martial arts called Bichun. In that time he learns that Mongols murdered his father, and so he joins a resistance against them. He does not know, however, that Sullie married a Mongol noble believing that Jin-ha was killed at war. Can they possibly fulfill their vow?
