Tsuyoshi (Komoto Junichi) visits his lonely grandfather at the hospital, and discovers that everyday the old man receives a mysterious postcard with a picture of a cherry blossom tree. When Tsuyoshi meets a taxi driver (Kawahara Sabu) who claims he knows the location of the postcard's tree, they head out on the open road together to find those cherry blossoms. Along the way, they pick up another traveler who's just as wacky.
