A young man moves into a run-down apartment building and soon gets into a relationship with a neighbor. Both the characters and the building have traumatic histories, and over time the ghosts of their past come to light.

Ko-bong has a huge crush on Gye-soon who works at a fast food restaurant without knowing that the girl he love is a spy from North Korea.

He loved those who suffered from Hansen’s disease as himself; served the country with love even after being sentenced to life imprisonment; and even adopted his enemy’s son as his own son. Son Yang-Won was a saint, the likes of which could not be found even in world history. However, the movie depicts a plain person who also suffered with humane agony and dealt with the hidden side of the person who overcame the pain.

Ji-eun, a member of North Korea's dance troupe and the daughter of the North Korean leader, escapes to the South after one of their perfomances. Eager to explore the liberal life in Seoul, Ji-eun searches for a new life of freedom in South Korea. She soon comes across Joon-ho, a leader of a local rock band. Their relationship then takes unexpected turns as they become closer to each other. Meanwhile, the intelligence agency in South Korea learns of a conspiracy being orchestrated by the American CIA to disrupt the peace on the Korean peninsula; the CIA plots to secretly kidnap Ji-eun. Secret forces from the North and South reluctantly agree to work together to prevent a possible war between their two countries.
