Secretly Greatly

Won Ryu-hwan, a North Korean agent trained by the North Korean elite special forces since young, was sent to South Korea as a spy. Ryu-hwan takes up the identity of Bang Dong-gu, a goofy and mentally challenged young man while two other spies, Lee Hae-rang and Ri Hae-jin take up the personas of a young wannabe rock star and a high school student respectively. As time went on without receiving any orders from North Korea, they got used to their lives in the small town and slowly became attached to the people living there as well. However, their peace was disturbed abruptly when they were ordered to take each other’s lives, or risk death at the hands of an elite hit team.
