As the USA and Soviet Union race for supremacy in the 1960s, Premier Khrushchev sizes up his rival, President John F Kennedy. Presenters 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 could not 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.
