Remember those old-time, often black and white science-fiction movies made in the 1950s? The Thing, THEM!, The Blob? You know, those funny old flicks that kicked off the modern era of aliens as entertainment that are so dated now? They can be fun to watch today with their stereotyped scientists, absurd monsters, and amateurish special effects that are seldom believable.If that's what you got from those old movies, if you didn't sense the underlying controlling message, take another look: there was more to those old movies than meets the eye.One Door Opens sets the stage to expose the Agency, the secret organization headquartered in the White Sands desert of New Mexico, wielding unquestioned power and determining the course of humanity through the administration of extraterrestrial technologies salvaged from an alien spaceship crashed in the Arctic a few years after World War II and they've been running things ever since.This short story also introduces the tight-lipped owner of a tavern called the Bunker, built in the Cold War and forgotten in the desert but convenient to the solitude of White Sands. It was the only place that ever felt like home to Walt. There was plenty of flat quiet surrounding the Bunker so it was easy to tell if something was coming a mile away, and that suited him to a tee.The building was big, windowless, had only one door, and blended into the landscape - all in the plus column for Walt. But the organic Adobe architecture was a façade concealing the actual construction and real purpose of the structure. Lead-lined, reinforced concrete slabs were stacked into thick walls, forming the earthen-style monolith, built to keep anyone inside alive.That is unless Syl shows up. She's Walt's young protégé and has a habit of making people die.Everyone thought the building was to keep them safe from an Iron Curtain atomic blast, and it would, but there were other dangers in the desert, and the Bunker was the only place safe from them.
