Charlie's Country (2013)

Blackfella Charlie is getting older, and he's out of sorts. The intervention is making life more difficult on his remote community, what with the proper policing of whitefella laws that don't generally make much sense, and Charlie's kin and ken seeming more interested in going along with things than doing anything about it. So Charlie takes off, to live the old way, but in doing so sets off a chain of events in his life that has him return to his community chastened, and somewhat the wiser.

Unfortunately the movie Charlie's Country is not yet available on HBO Max.
