No meteorites hit Earth, no terrorists put the world in danger, no atomic war was started, but something did go wrong. Contact between most towns on Earth has been severed. A small ring-like area in Eastern Europe still has electricity, and maybe even life is being reported from the Space. What military forces find outside the Ring is shocking.
