Secretly, Greatly (Korean: 은밀하게 위대하게; RR: Eunmilhage widaehage) is a 2013 South Korean action comedy-drama film starring Kim Soo-hyun, Park Ki-woong, and Lee Hyun-woo, who play North Korean spies who infiltrate South Korea as a village idiot, a rock musician, and a high school student, respectively. They assimilate to small-town life while awaiting their orders, until one day, due to a sudden power shift in the North, their mission turns out to be an order to commit suicide.
The film is based on the 2010 spy webtoon series Covertness by Hun. Upon its release on 5 June 2013, the film broke several box office records in South Korea: the highest single-day opening for a domestic film, most tickets sold in one day for a domestic film, the biggest opening weekend, the highest-grossing webtoon-based film, and the fastest movie to reach the million, two million, three million, and four million marks in audience number. Movie pundits attribute its success to a large teen audience turnout.

Synopsis
A group of spies called the 5446 Corps were trained by North Korean elite special forces since their youth, ostensibly towards the lofty goal of unifying Korea. They are ambitiously dispatched to South Korea, where each assumes a disguise. The story protagonists are three men who masquerade as a village idiot, an aspiring rock musician, and a high school student. As time passes without further orders from the North, the three spies gradually get used to life as ordinary members of a small neighborhood until one day, their mundane lives are turned upside down when a "secret and great" mission is suddenly assigned to them. Due to the events of the 2002 Second Battle of Yeonpyeong, South Korea demands the names, location, and rank of 30 North Korean spies active in the South, promising financial aid to the North on the condition that Pyongyang turns in their spies. To prevent the 5446 Corps from falling into enemy hands, the North Korean government orders them to take their own lives. Meanwhile, their North Korean army instructor, Kim Tae-won, crosses the border to eliminate those who refuse to obey.
