The story begins with Cha Dal-geon, a passionate and struggling stuntman raising his orphaned nephew, Hoon. Their
strained relationship shatters when Hoon boards a fateful commercial flight to Morocco and dies in a catastrophic terrorist crash alongside a delegation of Korean youths. Consumed by grief and desperate for answers, Dal-geon flies to the crash site. There, he spots a survivor from a leaked video—a man who was supposedly on the doomed plane—and realizes the tragedy was no accident.Back in Seoul, Dal-geon crosses paths with Go Hae-ri, a sharp, ambitious undercover agent for the National
Intelligence Service. Initially dismissive of Dal-geon’s wild conspiracy theories, Hae-ri soon discovers undeniable proof that the plane crash was deliberately orchestrated. The catastrophe was actually a high-stakes corporate sabotage mission masterminded by John & Mark, a defense contractor locked in a fierce multibillion-dollar battle with South Korea’s Blue House to secure a major fighter jet acquisition contract.As Dal-geon and Hae-ri dig deeper, they uncover a terrifying web of institutional corruption, betrayal, and political greed that reaches the absolute highest levels of the South Korean government. Powerful figures, including the Prime Minister and the President himself, are willing to bury the truth and silence anyone who gets in their way. Every step the duo takes puts them in mortal danger, hunted by ruthless assassins led by the lethal agent Jessica Lee and a psychopathic mercenary named Jerome.Despite relentless attempts on their lives, framing, and betrayal from within their own agency, Dal-geon uses his exceptional stuntman resilience and combat skills to stay alive, while Hae-ri leverages her intelligence network to expose the conspirators. They manage to secure a whistleblower and vital digital evidence, but systemic corruption repeatedly blocks justice, as corrupt judges and politicians manipulate the legal system to protect the guilty.The narrative reaches its gripping climax when a desperate faction within the government forces Dal-geon into a corner, ultimately leading him to believe Hae-ri has been killed. Believing he has lost everything he fought for, a broken Dal-geon accepts a contract to become a high-level mercenary for a shadowy private military firm. Meanwhile, Hae-ri survives and rises to become a powerful, ruthless lobbyist, both characters unknowingly operating on opposite sides of the same dangerous global syndicate. In the final tense moments, their paths cross again in a tense standoff, setting the stage for an inevitable reckoning as they realize the conspiracy runs far deeper than they ever imagined.
