Secretly Greatly
(은밀하게 위대하게)
Ryu-hwan is a North Korean elite spy trained to kill. He was sent two years ago as a sleeper agent in Seoul. He lives in a small apartment owned by an old lady, for whom he also works. He knows everyone in the neighborhood but is only seen as that naive young guy with the mind of a child. Suddenly two other spies arrive in the area: Hae-rang pretends to be a rookie guitar player in a rock band, and Hae-jin a regular student. Ryu-hwan helps them to settle and get used to their new life, until they are ordered to commit suicide after a change of power in North Korea.
