Researcher Mutsugoro takes his family to a remote and uninhabited island near Hokkaido, to study the local population of wild bears. Nearby poachers make his life difficult, and he "inherits" an orphaned bear cub, whom the family call Donbe and raise as one of their own.
Unfortunately the movie Donbe's Story is not yet available on HBO Max.
