In the third and final film in the series, Lucy Worsley reveals the historic myths and deceptions told following the United States' emergence as a superpower after the Second World War. We often remember the 1950s and early 1960s in America as a golden era of abundance, harmony and the American dream made real. This film reveals that to be a carefully constructed illusion. In truth, the era of America's supremacy was a time of government deception, racial conflict and fears of nuclear annihilation.
