Dr. Kim Myung Guk has been missing for three years. Ever since a terrorist organization tried to capture him for his development on nuclear weapons. But now, the National Anti-Terror Service (NTS) has information that the organization has found him.
With the President's daughter kidnapped, the NTS must join forces with Son-Hyuk and his men in order to get her back without giving the terrorist what he wants.
Son-Hyuk and the DIS are requested to move their offices into NTS. Hye-In plans to use Jung-Woo's desire for her to gather classified information for the DIS.
