Replying...
Intro. Cha Dal-geon, a stuntman whose life was ordinary, suddenly fell apart when his nephew died in a mysterious plane crash. At first it was thought to be an ordinary technical accident, but Dal-geon discovered something odd—and one important fact: someone had deliberately crashed the plane. In his search for the truth, he meets Go Hae-ri, a secret agent from the Korean intelligence agency. From there, the story turns into a high-level conspiracy involving government officials, international arms companies, and dirty political games. The deeper they dig, the clearer it becomes that the tragedy was no mere accident—but part of a grand scheme for money and power. Dal-geon, who was originally just an angry uncle, turns into a person who is ready to fight the system, even if he has to lose everything.
