Seven Days in May
Fletcher Knebel
 The story is set several years into the continued cold war between the United States and the Soviet Union, not long after a stalemated conflict in Iran similar to the Korean War (the novel gives the date of May 1974, while the film shows a California license plate with a 1970 registration decal, a Texas 1970 license plate, and an electronic map of active military bases displaying the date of May 9, 1970). With the ever-present possibility of nuclear war and mutually assured destruction, U.S. President Jordan Lyman signs a nuclear disarmament treaty with the Soviet Union, with both nations simultaneously destroying their nuclear weapons under mutual international inspection. The ratification produces a wave of public dissatisfaction, especially among the President's opposition and the military, who believe the Soviets cannot be trusted. As the debate rages, a Pentagon insider, United States Marine Corps Colonel Martin "Jiggs" Casey, becomes aware of a conspiracy among the Joint Chiefs of Staff (JCS) led by his own superior officer, the charismatic Air Force General James Mattoon Scott. He uncovers a shocking secret: Scott and his JCS cohorts, along with allies in the United States Congress, led by Senator Frederick Prentice and influential media personality Harold McPherson, are plotting to stage a coup d'etat to remove President Lyman and his cabinet seven days hence. Under a procedure known as ECOMCON (Emergency COMmunications CONtrol), the nation's telephone, radio and television network infrastructure is to be seized by a secret United States Army combat unit secretly created by Scott and based near Fort Bliss, Texas. From their headquarters within a vast underground nuclear shelter called "Mount Thunder" (based on the actual continuity of government facility maintained by the U.S. at Mount Weather in Berryville, Virginia), the general will use the power of the media and the military to prevent the implementation of the treaty. Although personally opposed to President Lyman's position, Casey is appalled by the unconstitutional cabal. He alerts Lyman and his inner circle: Secret Service Director Art Corwin, Secretary of the Treasury Christopher Todd, presidential adviser Paul Girard, and United States Senator Raymond Clark of Georgia, a political and personal ally of the president. Lyman sends Casey to New York City to ferret out secrets that can be used against Scott, which forces Casey to cruelly deceive the general's former mistress, the vulnerable Ellie Holbrook. He leaves in possession of letters between her and General Scott which would compromise his moral credibility with the public. The president also sends the aging, alcoholic Clark to El Paso, Texas to see if he can locate the base (covertly known as "Site Y"). Girard leaves for the Mediterranean to obtain a confession from Vice Admiral Farley C. Barnswell, the 6th Fleet commander stationed on the USS Kitty Hawk, who knows of the plot but decides not to actively support or oppose it (responding through a code involving the Preakness Stakes horse race). Girard gains the admiral's written confession, and telephones the President before boarding a plane from Madrid back to Washington. Girard is killed when the passenger airliner he is on crashes into a mountain in Spain. Clark finds the secret base, but is taken captive by conspirator Colonel Broderick and held incommunicado. Clark is visited by the base's deputy commander, Colonel Mutt Henderson, a friend of Jiggs, and who knows nothing of the plot. The senator persuades Henderson to help him escape, but at the airport, while Clark makes a call to the president, Henderson is arrested by Scott's men. A showdown with Scott is scheduled in the Oval Office. The president confronts him and demands his resignation "along with the other members of the Joint Chiefs involved with this treason." Scott initially denies any guilt, claiming that the president had verbally approved the secret base in Texas. When Scott fails to convince the president of his innocence, he begins to talk freely and launches into a debate with Lyman, arguing that approval of the treaty would weaken the U.S. and lead to an attack by the Soviets. Lyman tries to reason with Scott, explaining that a military coup would send a signal that could result in a preemptive strike by Moscow. Scott is unmoved, stating that he feels the American people are behind him and his position. Lyman considers using the blackmail letters, but decides against it. Scott is allowed to leave. Shortly thereafter, Scott briefs the other three members of the JCS, who are close to panicking. He demands everyone stay in line, pointing out that the president does not seem to have the evidence he would need to bring charges of treason successfully. Somewhat reassured, the others agree to stick to the plan to appear on all television and radio networks simultaneously on Sunday to denounce the president. However, Lyman first holds a press conference where he demands the resignation of Scott and all members of the Joint Chiefs of Staff. The conference is interrupted when an attaché from the U.S. Embassy in Spain arrives. He has brought the handwritten confession that Girard obtained from Vice Admiral Barnswell, which survived the crash in Girard's cigarette case. A copy is given to Scott and the other officers in on the plot, who have no choice but to resign and call off the coup. The ending has Lyman addressing the American people on the country's future.
