In the 1990s, rumors of recovered crashed flying saucers emerged from a phantom, top secret air base in a remote corner of Nevada's atomic test range, and the terms 'Area 51,' 'Dreamland' and 'Groom Lake' inspired hordes of UFO believers and researchers to descend on a tiny town on the border of Area 51 to trade stories, whisper secrets and watch the skies. Filmed over several years of two UFO buffs on their own personal search for the truth, 'Alien Highway' is about the people whose passionate obsession created a unique cultural phenomenon that flourished for a time in an obscure little community that happens to exist on the border of America's Twilight Zone.
