With exclusive access to the Prince of Wales in his 70th birthday year, this intimate and revealing film follows the British heir to the throne over the course of a year, both at work and behind-the-scenes.

Filmmaker John Bridcut also speaks to those who know him best - his wife, The Duchess of Cornwall, and his sons, Prince William and Prince Harry, both of whom speak about their upbringing as teenagers and their feelings about the Prince's working life.

Prince Charles’ 70th birthday marked half a century of involvement in public affairs, championing environmental and social issues, ranging from plastic waste and global warming to lack of opportunity for young people, long before they reached the mainstream. This documentary charts the Prince's working life at a time when he took on an increasing amount of duties in support of the Queen. He is seen on working visits to County Durham, Cornwall, and the Brecon Beacons, and at home at Highgrove in Gloucestershire and Birkhall in Aberdeenshire.

The film also features behind-the-scenes footage of the Prince with the Queen in Buckingham Palace, at the time of the Commonwealth Heads of Government Meeting in April, when the Prince was named as the next head of the Commonwealth, as well as the stunning ceremonial welcome given to the Prince in the Pacific Island Republic of Vanuatu when he was invested as a high chief. His visits to three Caribbean countries struggling to recover after hurricanes Irma and Maria are also included.

Enjoy this revealing and intimate portrait of the longest-serving heir to the throne who, though he has done so much, feels that there is still much more he must do.
