Ancient Native American legend of the Bone Eater rises up and begins terrorizing the local townspeople.

In Sweet Water, the ambitious entrepreneur Dick Krantz is constructing a resort in the middle of the desert - under the protest of the Katonahs. When three workers find some Indian relics and bones in a ditch in the site, they accidentally release the giant skeleton-like creature known as Bone Eater, and their bones are devoured by the monster. Biracial Sheriff Steve Evans, a.k.a. Running Wolf, is in charge of the investigation of the disappearance of the workers, being pressed by Krantz to arrest the protesters. But the Bone Eater attacks and kills other locals, while Chief Storm Cloud seeks an ancient Tomahawk capable of destroying the evil creature.—Claudio Carvalho, Rio de Janeiro, Brazil
