Secret Reunion (2010)

In the clandestine world of international espionage, an elusive assassin known as "Shadow" from North Korea is dispatched to Seoul on a mission to eliminate a prominent dissident. His partners in this covert operation are two dormant agents — Son Tae-soon, the vigilant lookout, and Song Ji-won, a master of combat. However, their meticulously planned operation doesn't account for the relentless pursuit of Lee Han-gyoo, an astute operative from the South Korean National Intelligence Service. As Han-gyoo closes in, he underestimates the deadly skill and ruthless tenacity of the North Koreans. Living up to his name, "Shadow" evaporates into thin air, while Ji-won narrowly escapes capture. Now a fugitive in a foreign land, Ji-won is caught in a predicament — he can neither return to his homeland, where he's branded a traitor, nor can he seek asylum, as it would spell doom for his family left behind in North Korea. Meanwhile, the failed operation leaves Han-gyoo discredited and dismissed from the intelligence service. Years pass and destiny contrives an unexpected reunion between Ji-won and Han-gyoo. Their old rivalry resumes, but with a twist — they now find themselves in a precarious business partnership, each intending to outsmart and extract information from the other. In this high-stakes game of deception and survival, their loyalties are tested, alliances shift, and intrigue abounds, setting the stage for an unforgettable battle of wits.
