In the summer of 2007 a painter in his forties travels to Paris to escape arrest for smoking marijuana, leaving his wife behind in Korea. While there he meets an ex-girlfriend and is introduced to a small community of Korean artists.

"Night and Day" is centered around the mixed emotions found in traveling. Characters in the film are Sung-nam Kim, an artist selected by the Korean government that escaped from Seoul and currently resides in Paris, student Yoo-jung Lee studying painting in Paris, Sung-in Han waiting for her husband Sung-nam Kim, and North Korean Kyeong-su Yun also studying in Paris.—Eun-wook at Luna Park
