In the year 2091, inhabitants of a small city Postville became the object of a great experiment. A virtual prototype of a real world was created, which existed and developed independently. This experiment, called Utopia, became so successful that it was decided to open it to the whole world. Very soon Utopia became so popular that almost all people of our planet got connected to it and abandoned the real world. The rest unplugged people were found that Utopian AI program, Mastermind, had taken control of all people living in the city. Nobody could leave virtual world now, which eventually led the real world to collapse.
