Park Ranger Don Morgan’s ordinary life is disrupted when he encounters a UFO sighting in the barren, desolate park where he lives. A mysterious and strange power failure disables all electronic devices and communication systems, leaving a group of hikers stranded in the park and causing a small plane to crash. In the sweltering heat, Don is tasked with guiding the survivors through what seems to be a deserted military testing site known as “ZONE-X” in search of water.
