Soviet radicals upset with the thawing of the Cold War explode a nuclear weapon in Russia, setting off a series of events that may very well trigger World War III. The president (Martin Landau) has been isolated after a helicopter accident and must outwit government and military officials who are attempting to go forward with the war. The film centers on the relationship between a pair of American pilots who have been ordered to bomb the U.S.S.R. and the attempts by some factions to bring them home before global Armageddon.
