Taking place in the not too distant future, North and South Korean governments are
on the verge of re-opening the Kyungui Railroad, which connects the two Koreas as
a further step toward reunification, when Japan refuses to accept the decision, claiming
rights to the railway lines based on official documents imprinted with the royal
seal of King Gojong of Joseon a century ago. Yet an age old conspiracy is uncovered
where the royal seal with which King Gojong signed the documents is suspected to
be fake. It is a race against time and hidden agendas as the South Korean President
(Ahn Sung-ki) employs the outspoken historian Choi Min-jae (Jo Jae-hyeon) and the
descendant of the Joseon royal bloodline Kim Yu-shik (Kang Shin-il) to find the authentic
seal and prevent the history of Japanese occupation from repeating itself. In the
meanwhile, Japanese economic sanctions divide the Korean government, and its armed
forces appear on the border of Korea threatening its sovereignty. Eventually, the
authentic royal seal is found and Japan apologizes for its occupation.
