The movie is about a north american indian family who have twin boys, 1 boy is abducted and raised by another indian tribe. The boys grow up and are reunited during battle when the 2 boys face each other in battle. Only the narrator speaks english I can't remember for sure but it might have subtitles... its been a very long time since I have seen it (25 years) the setting is before the white man came
