Ryu and Koichi are brothers who have been separated by divorce: stoic, grounded 12-year-old Koichi lives dutifully in coastal Kagoshima with his mother and grandparents, while 10-year-old tearaway Ryu is living it up with his deadbeat musician dad in urban Kyushu. Meanwhile, the Kyushu train line connecting these two cities is nearing completion and Koichi hears a rumour that when the first two trains pass each other a miracle will occur and wishes will be granted to all those who witness it. With this in mind the brothers set out with a plan to reunite their family.
