It is the early 21st century, and Ed Stone says he's been in suspended animation since the 1930s--put there by aliens who have sent him on a mission: convince the nations of the world to build a massive vault, in which humanity's billions will lie in suspension and survive the Earth's impending destruction. And, the strangest thing of all is everybody believes him.
