While travelling across country wasteland, Zoe stumbles upon a horrific crime: a gang of rednecks slaughtering two native boys. Her brave attempt to save one of the boys seals her fate and she is captured and viciously beaten. When an Indian shaman finds her clinging to life in a shallow grave he rouses the spirits to try and save her. However, as the waning moon casts Zoe into shadow, the spirit of an ancient Apache warrior is roused and takes host of her limp body. Zoe now walks amongst the living, hell-bent on revenge. One by one she seeks to slaughter the men who hurt her while the clock ticks away on her quickly decomposing body.
