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. He goes on the run, seeking his wife and daughter who were sold as slaves to China, only to discover their corpses. When he learns that an ex-colleague was behind their deaths, Dong-cheol goes on a vendetta for revenge, defecting to the South to chase his family's killer. 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. The South Korean intelligence service, a member of which frames Dong-cheol for the murder, goes on the hunt for the beleaguered former spy. The manhunt is led by Min Se-hoon, a colonel and drill sergeant with whom Dong-cheol shares a past, and Kim Seok-ho, the director of the NIS.
