Enemies Foreign And Domestic is a domestic terrorism thriller set "in the near future." The story begins on opening day of the NFL season, when bullets begin to rain down upon the upper deck of a packed football stadium. A panic stampede ensues, leading to mass casualties. The alleged sniper is found holding a smoking assault rifle, and is killed by a police marksman.
One week later, Congress bans the private possession of all semi-automatic assault rifles. Gun owners are given one week to turn in their semi-automatic rifles, or face a five year mandatory sentence.
The plot revolves around the true identity of the actual sniper. The alleged sniper killed at the scene may be a patsy, and many Americans refuse to turn in their banned weapons, leading to a civil crisis in the nation between supporters of the 2nd Amendment and a federal government trending toward tyranny.
