Synopsis One winter, Yu Jun-sang and Lee Joon-hwa, the two members of a band J and Joy 20 get on a flight to Japan with an impulse to film a music video. They set off to Japan, without any actors or themes prepared and armed only with an ambitious plan to make a song for spring. As Japanese musical actor Nakagawa Akinori and two Korean actors Kim So-jin and Jung Soon-won gather together, a joyful production of the music video unfolds on a snowfield with Mount Fuji in the background. Spring Song is a record of passionate creations and a pleasant aria about artists with simple and pure minds.
