In the 1970s, South Korea is under the absolute control of President Park, who controls the KCIA, the organization with an edge over any branch of government. The director of the KCIA, Kim Gyu-pyeong (Lee Byung-hun), is nearly the second-in-command, but faces rivalry from the president's security chief. Amid a reign of fear, a former KCIA director, Park Yong-gak (Kwak Do-won), who knows all about the government's obscure and illegal operations, goes into exile, and testifies in front of the U.S. Congress, opening the floodgates to the investigation of Koreagate. As tension escalates, stifling political maneuvers by those desiring power collide explosively. With his mission accomplished, Kim returns to South Korea and faces conflict with Kwak Sang-cheol, President Park's bodyguard.
