Yoshikawa, who works for a travel agency, is visiting a town in the suburbs to do research for a new tour project. However, Yamakita, which used to be a prosperous “railway town”, has no sign of life in front of the station and the shopping street is almost closed. Halfway through her research, she walks along a nearby riverbed and discovers a man, Doi, who is diligently skimming stones. They look for their favourite stones, start playing games with branches, and spend time together as if they were children again. But as the sun sets, the time they have spent together is coming to an end.
