“One Shining Day” is a digital omnibus feature in commemoration of the 60th anniversary of Korea Independence Day. Three Korean young filmmakers show a closer relationship between Korea and Japan with their own vision.
Segment 1 - The Treasure Island (dir. by Kim Sung-ho): Mie comes to Korea in search for a keepsake, which her grandpa left behind when going back to Japan from Jeju Island due to Korean Liberation. She and her friend, Eiko meet a variety of Korean on their journey to Jeju Island. One day they get threatened by rowdies, but they find the way out of the dangerous situation. The journey to Jeju Island makes two Japanese girls realize what friends are good for even in a difficult time and find out who really they are.
Segment 2 - Good-bye (dir. by Kim Jong-kwan): Jong-hwan defrauds people of money with a laptop-computer to make money for meeting his mother who lives in Japan. He is a kind of trouble maker home and even at school, but keeps taking a risk of doing a dangerous defraudation looking forward to reunion of his mom and him.
Segment 3 - The Beautiful Strangers (dir. by Min Dong-hyun): On arriving at the airport, Ishida starts running to catch the flight to Japan. He ends up missing his flight by bumping against Go-ny, working at a duty-free shop at the airport. After a while, they get to meet up once again at the airport and spend some time together. It's a story about a conversation of two people from different countries and different languages.
