Sheep Herd Nation takes place in America's future in a parallel New York City named "The Empire City". The mayor, Jonah Jeplin, installs a drone database that spies on the American people in order to better society as a whole and keep everyone safe. Dan Rivers, a writer for the City Times, discovers Mayor Jeplin has sold drone plans to enemies of the United States, and tries to expose him. While Rivers is in the Empire City at a baseball game with his son, Jeplin's drone system gets hacked and a massacre begins. Dan and his son find safety but become separated, and the quest quickly turns into not only trying to find his son, but to figure out who hacked the system and why. As Dan Rivers soon finds out though, it is either save his son, or save the world.
