In the near future, North and South Korea establish a "Peace Village" in order to try out during their discussion for reunification. Both nations have North and South Koreans live there for a year to help create a positive image of reunification. However, due to an error, Joo-hyung, a famous South Korean pianist, and Na-gyeong, the daughter of a high-ranking North Korean government official, are placed in the same house. For the sake of reunification, the two decide to agree to share the house for a year.
