Secret Agent

After losing his sovereignty to Japan through the Eulsa Protection Treaty, Gojong ordered Lee Yong-ik to hide gold bars and military funds to restore his sovereignty. When King Gojong was forcibly abdicated, the army was disbanded. At this time, So-chun, daughter of Park Seong-hwan, who committed suicide by protecting himself as a soldier, gathers in the Dongsanbang. Dongsanbang's governor Dongsandae completed the patriotic bulwark as a patriot and passed it on to the believers from the military service. Among them, Min Jeong-gyo and So-chun fall in love and get married early, and they play an active role in the ranks of the Great Victory and Salvation Kingdom when the gold hidden by Lee Yong-ik is robbed by the Japanese.
