In March 2018, a Japan Railway line linking Shimane and Hiroshima Prefectures in western Japan stopped operating, ending its 88-year history. The Sanko Line once thrived as an indispensable means of transportation. But the number of passengers gradually fell as more people started using cars, and the local population declined. As train buffs gather to bid farewell, a group of residents starts exploring ways to turn the parts of the railway into a tourist attraction, and revitalize their hometown.
