Plot Ji Dong-cheol was once one of the top special forces agent in North Korea, but after a change in political system, he was abandoned by his government while on a mission.

Now living incognito, he searches for his nemesis during the day, and at night works as a personal chauffeur for Chairman Park, a business executive with ties to Pyongyang. One night the chairman is attacked and killed by an assassin, but not before handing over a special pair of glasses to Dong-cheol.
