After a symphonic music career in Europe cut short by hearing loss, Ao (Oizumi Yo) returns home to run his family's farm in Hokkaido alongside younger brother Roku (Sometani Shota). Roku carries on the family legacy of wheat farming, but Ao becomes obsessed with starting a winery specializing in Pinot Noir. The brothers' troubled relationship is upset further when one day mysterious yet charming Erika (Ando Yuko) pitches camp in a neighboring field. A Drop of the Grapevine is the second of director Mishima Yukiko's Hokkaido Trilogy, an intended triptych that features the natural bounty and scenic landscapes of Japan's northern island.
Unfortunately the movie A Drop of the Grapevine is not yet available on Disney Plus.
