After his father's botched espionage mission, North Korean Myung-hoon and his young sister Hye-in are sent to a labor prison camp. In order to save his sister's life, Myung-hoon "volunteers" to become a spy and infiltrates the South as a teenage defector. While attending high school in the South (his cover), he meets another girl named Hye-in and rescues her when she comes under attack by school bullies. South Korean Intelligence soon discovers Myung-hoon's activities and begins tracking him, all the while as his own government sends a vicious assassin to eliminate him.
This was the type of Korean movie that centers on the conflict between North and South Korean. Both countries use each other to gain intel as well as influence military and government officials to bolster their patriotism. The director did a good job showing the naiveté of the youth in their society as well as the manipulation of those in power to balance the relationship of both countries. Myung-hoon the son of the disgraced spy becomes an assassin for the North in order to save his sister from the labor prisons they were sent to because of their father killed for being a traitor.
Myung-hoon travels south and begins working with spies in the south. The couple that takes him in has their own agenda but gives Myung-noon cover for his missions for the North. He tries to keep a low profile but becomes interested with a young lady in school with the same name as his sister. When two Secret government factions become at odds with each other. Myung-hoon gets caught in the middle of this conflict and the group agrees. Kyung-goon has to die. The pain Myung-boon goes through with trying to understand why all of this is happening to him and how he did everything right, shows how the mentality of a young man blinds him of the reality of corruption and the ongoing conflict between the two countries. The betrayal from his own country and his love for his sister, distorts his life's meaning. This movie has you wondering what side is right. The manipulation is done by both sides even though one side is communists. The underline story is political and social, but the action and espionage keeps you engaged. Good movie.
