Cha Dal-gun (Lee Seung-gi) works as an underrated stuntman, while simultaneously taking care of his orphaned nephew, Cha Hoon (Moon Woo-jin). Although they have a fairly loving relationship, Hoon argues with his uncle before he leaves to go on a field trip to Morocco. Just before the plane takes off, Hoon sends a video of himself encouraging Dal-gun to continue following his dream to become a master in Taekwondo.
At a drama set Dal-gun watches a report of a plane crash that killed over 200 civilians due to structural failure. He is completely shocked when he realizes that it is the exact same plane his nephew had taken to Morocco. With his world now turned upside down, Dal-gun travels to Morocco to attend the funeral for all the victims of the plane crash, grieving for the loss of his nephew.
Dal-gun is about to return home, when he recognizes a supposedly dead passenger from the video his nephew had recorded. He manages to confront the man and slowly begins to realize that the plane crash was not at all because of a malfunction. However, any evidence he finds is mysteriously erased and his life is threatened whenever he tries to prove to others that the plane crash was not an accident.
As the situation quickly becomes more heated, he is forced to become partners with Go Hae-ri (Bae Suzy), a covert operative for the National Intelligence Service striving for a promotion. Determined to find out the truth behind the accident, Dal-gun and Hae-ri embark on an investigation that leads them deeper and deeper into a tangled web of corruption.
