A U-2 spy plane flight over the island of Cuba produces photographs of Soviet nuclear missiles being installed. Though American missiles have been installed near Russia, the U.S. decides that no such weapons will be tolerated in Cuba. The resultant standoff brings the U.S. and the Soviet Union to the brink of war. The crisis finally ends with a secret deal in which the U.S. removes its missiles from Turkey in exchange for the Soviets removing the Cuban weapons.
