14-year-old Takuya lives in a rural town near mountains and rivers. His 29-year-old uncle Koji works as a graphic designer in urban Tokyo. Koji's father dies and Takuya is arrested for attempted robbery-the two young men must now face a crucial crossing in their lives. The concluding chapter to director Higashi Yoichi's "boy and river" trilogy, the film highlights contemporary themes like family, adolescence, and the healing properties of nature. The wild but beautiful Kuma River stars as a threatening symbol for the boy's rite of passage. Supernatural beings reign in the mountains above the village.
