Beyond being in the same class at Shermer High School in Shermer, Illinois, Claire Standish, Andrew Clark, John Bender, Brian Johnson and Allison Reynolds have little in common, and with the exception of Claire and Andrew, do not associate with each other in school. In the simplest and in their own terms, Claire is a princess, Andrew an athlete, John a criminal, Brian a brain, and Allison a basket case. But one other thing they do have in common is a nine hour detention in the school library together on Saturday, March 24, 1984, under the direction of Mr. Vernon, supervising from his office across the hall. Each is required to write a minimum one thousand word essay during that time about who they think they are. At the beginning of those nine hours, each, if they were indeed planning on writing that essay, would probably write something close to what the world sees of them, and what they have been brainwashed into believing of themselves. But based on their adventures during that nine hours, they may come to a different opinion of themselves and the other four.

A retired special agent named John Matrix led an elite unit and has left the armed forces to live in a secluded mountain home with his daughter Jenny. But now he is forced out of retirement when his daughter is kidnapped by a band of thugs intent on revenge! Unbeknownst to Matrix, the members of his former unit are being killed one by one. Even though Matrix' friend General Franklin Kirby gives Matrix armed guards, attackers manage to kidnap Matrix and Jenny. Matrix learns that Bennett, a former member of his Matrix' unit who was presumed dead has kidnapped him to try to force Matrix to do a political assassination for a man called Arius (who calls himself El Presidente), a warlord formerly bested by Matrix who wishes to lead a military coup in his home country. Since Arius will have Jenny killed if Matrix refuses, Matrix reluctantly accepts the demand.
