Washington, D.C. - It is the summer of 1979. What remains of the United States is reassembling itself after a nuclear war with the now-vanquished Soviet Union. Detective Benjamin Fuller is called to investigate the murder of a U.S. Senator, Graham Collins. One of the leads involves a masked figure near the scene of the crime. Fuller suspects that the Anarchists, a terrorist group determined to overthrow the interim American government, is to blame. Meanwhile, Henry Cooper, veteran Air Force fighter pilot, becomes a member of the Captiol Garrison Security Force at the Madison Building, one of numerous senatorial offices in the city. There, Henry quickly falls for Emma Aiden, orphaned niece and staffer of Senator William James Aiden, who himself becomes a target for the Anarchists. Among those present during an assassination attempt on Senator Aiden's life is the masked individual. Fuller and Henry join forces and must race against the clock when another Senator is kidnapped by the Anarchists. Henry believes the masked man is at the root of all of it -but Emma believes otherwise.
