Arriving in South Korea, Myung Hoon is taken in by secret North Korean spies and enrolls in high school, where he befriends another Hye In (Han Ye Ri) after rescuing her from bullies. As he attempts to complete his mission, political upheaval in North Korea suddenly makes Myung Hoon a target, with an assassin sent to eliminate him. Now he must fight not only to complete his mission but to survive and potentially save his sister. This is a 2013 South Korean espionage thriller film co-written and directed by Park Hong Soo.
