Park Ranger Don Morgan is torn from his routine life, when he stumbles upon a UFO visitation in the arid, deserted Park Area where he resides. An inexplicable, bizarre power outage knocks out all electronics and communications, stranding a carload of hikers in the park, and downing a small plane. Searching for hydration in the blistering heat, Don must lead the survivors across an apparently abandoned Military Testing area called “ZONE-X”.
