Aides rush in and out of the White House Situation Room, swarming around the map of Berlin spread across the table before President John F. Kennedy. All eyes carefully assess the markers on the city's layout, indicating the division between West and East and the area where two opposing lines of tanks stand facing each other.
Tensions between the Soviets and Americans have reached a climax at Checkpoint Charlie. Any misstep could spell doom for the entire world. As Kennedy and his allies weigh risks and alternatives, an obscure document makes it to the President's desk. The words on the page describe an attack unlike anything the U.S. has ever launched, a strike so brutal that Kennedy himself becomes uneasy just by reading it.
The idea is almost immediately discarded, but then intelligence of a Soviet bomb detonating in Europe arrives. The tested weapon has unleashed an explosion hundreds of times stronger than Hiroshima and Nagasaki combined. The Americans are forced to reassess their lethal plan, bringing the world one step closer to the age of nuclear war.
