The oldest tribe on the planet, the hunter-gatherer Hadza is fighting for its survival. Recently the Tanzanian government granted the tribe's ancestral land to members of an Arab royal family as a hunting concession. Now, led by Hadza activist Richard Baalow, the tribe are fighting for their rights and this film follows that struggle told through the Hadza's own voices.

In 2007 National Geographic's Genographic Project discovered that the Hadza or Hadzabe tribe from a remote corner of Northern Tanzania was the oldest tribe on earth. Furthermore members of the tribe were found to have entirely unique DNA. They are one of the last remaining hunter gatherer tribes on the planet.

But now a Hadza development worker, Richard Baalow fears that his tribe will be evicted from their ancestral land and with that link broken, they will cease to exist. 'Hadza Voices' starts with Richard and his brother Naftali having just been arrested for breaching the peace at a meeting to protest the selling of their land to a group of wealthy Arab trophy hunters. .

But that is only part of the story. The Hadza are the subject of an extraordinary amount of outside interest: academic, developmental and voyeuristic. Many of these outsiders have been tolerated or even welcomed by the tribe. But now their patience is wearing thin. Encroachment by other tribes, drought and wildlife tourism have all played their part in pushing the hunter gatherers to the very margins of their remote ancestral land and now there is no longer anywhere for them to retreat to. The time has come for them to demand their rights.
