Secret Reunion

Lee Han Gyu is a National Intelligence Service (NIS) agent. He is charged with heading a team with an important mission: It must protect a North Korean dissident – the cousin of Pyongyang's leader. But the mission is a total failure: Instead of sharing important intelligence with his commanding officers, Lee Han Gyu's team goes it alone. Meanwhile, Ji Won, a member of a secret unit of North Korean spies living in South Korea also runs into problems when one of his fellow spies defects to the South mid-mission. The target is assassinated, but both Lee Han Gyu and Ji Won are hung out to dry: The North thinks Ji Won betrayed his country, while the NIS thinks Lee Han Gyu is a liability.
