20 years ago, Kei, a 23 year-old highschool teacher, fell for a student, Hitoha, a beautiful girl, but lost her from a tragic car accident. He’s now a middle aged factory worker who has just quit the job to visit Klavan in Ukraine. There lies a beautiful railway called Tunnel Of Love, where people say you can meet with your deceased beloved one. A freight transport runs once a day and it is said that the train takes someone you wish to meet.
