The Berlin Wall rises, splitting the city from east to west. Then a stand-off between American and Soviet tanks at the crossing point, Checkpoint Charlie, brings the two superpowers to the brink of military confrontation. And fearing that they are falling far behind in the missile race, the Soviets prepare to test the biggest bomb ever exploded. As relations between the two sides deteriorate, we explore the importance of diplomatic back channels with hosts Nina Khrushcheva and Max Kennedy, relatives of the superpower leaders. We meet Max's father, Senator Robert F Kennedy, and his Soviet contact, Georgy Bolshakov.

This is the personal and political history of the Cuban Missile Crisis. Nina Khrushcheva is the great-granddaughter of Nikita Khrushchev and Max Kennedy is the nephew of President John F Kennedy, and the son of Robert F Kennedy.

As the USA and Soviet Union race for supremacy in the 1960s, Premier Khrushchev sizes up his rival, President John F Kennedy. Hosts Max Kennedy and Nina Khrushcheva, relatives of the superpower leaders, explore their rise to power - one wealthy, smooth-talking and Harvard educated, the other a hardened Soviet war leader from a peasant family. As they prepare to meet for the first and only time as world leaders, the stakes couldn't be higher: they are fierce rivals in the race to build ever more devastating missiles. This is the personal and political history of the Cuban Missile Crisis.

Nina Khrushcheva is the great-granddaughter of Nikita Khrushchev and Max Kennedy is the nephew of President John F Kennedy, and the son of Robert F Kennedy.
