Set around Ide, Kyoto Prefecture, Japan, Sasaoka Yuri and Ogawa Yosuke have been friends since they were children. They are crazed about bicycling. The two grow up through interacting with people in town.
The Amamiya Brothers, Masaki (Takahiro) and Hiroto (Hiroomi Tosaka), keep looking for their older brother Takeru (Takumi Saito) who disappeared one year ago. The three Amamiya brothers lost their parents when they were young. Since then, they relied only on each other. On the anniversary of their parents' death, Masaki and Hiroto expect Takeru to appear. Instead, they meet a person who has a clue on Takeru's whereabouts.
O Japão está prestes a receber o 23º tufão do ano. A matriarca Yoshiko, uma mulher idosa que mora sozinha, recebe a visita de dois filhos que não costumam ir à sua casa: Ryota, um escritor fracassado que ainda sofre com o divórcio e se arrisca fazendo bicos de detetive, e a filha mais velha, que tenta passar por exemplo da família, mas também tem seus problemas. Juntos, eles aguardam a chegada do tufão e relembram a morte recente do pai e marido.
