The second episode asks what will be the Prince of Wales's legacy for the Duchy, as senior staff prepare HRH Prince William for the day that he will succeed his father to become the next Duke of Cornwall. Meanwhile Prince Charles visits his latest challenge - Nansledan, a new town on the outskirts of Newquay, which is set to be twice the size of its predecessor, Poundbury. The film also examines The Duke's well-known passion for trees and for traditional rural crafts like hedge laying, and how these may shape the Duchy's future. And finally, as a new generation of Duchy farmers embrace their Duke's forward-thinking organic principles, Prince Charles talks emotionally about the challenges, criticism and successes that have marked his 50 years as Duke of Cornwall.
