Almost sixty years on, Castro's Cuban revolution continues to split world opinion as decisively as it did when that small band of bearded guerrillas first entered Havana. In the second part of Julien Temple's film we hear from the citizens of this extraordinary city how these young revolutionaries put their dreams into practice. With access to remarkable archive footage, we see how they set about building a brave new socialist world on America's doorstep. Now with Obama gone, Trump in the White House, Fidel dead and his brother Raul stepping down from the presidency, Havana too is about to step into the unknown.
