A medically retired Army Sargeant is drawn into an attempt to overthrow the Federal Government by a militia army when they try to kidnap the daughter of his best friend. The militia wants the man, a federal prosecutor, and his wife, an FBI analyst, to stop the prosecution of three of their members arrested for murder of an agent. When the threats intensify, the sargeant and the daughter begin to take the fight to the militia leaders. Things spiral downhill when they uncover the plot to assassinate the President and Vice-President in less than four days.
