Title: Healer (힐러)
Plot: A decades-old incident involving a group of five friends who ran an illegal pro-democracy broadcasting station during the Fifth Republic in South Korea brings together three different people—an illegal "night courier" with the code name "Healer", who possesses top-notch fighting skills, a reporter from a second-rate tabloid news website, and a famous journalist at a major broadcast station. In trying to uncover the truth from that 1992 incident, they grow into real, honest reporters, while dealing with the conflict between truth and fate.
