Anti-wilderness protesters have taken over a portion of eastern Utah. Stan Watson, driving to Moab, stops by the highway to walk his dog Speck, and encounters a woman who begs him for help. When he offers Lily and her injured husband a ride, they are confronted by armed men, and Stan is in for a nightmare he had not anticipated. Chased through the wildlands by rag-tag extremists riding off-road vehicles, Stan, Lily, and Frank, a lost reporter, face dehydration, starvation, and murder at the hands of their pursuers. When Stan and Frank become incapacitated, Lily and Speck lead them through the wilds in search of help and a way out of the hell that engulfs them.
