Featuring interviews with members of the Royal Family, this documentary is more than an intimate look at the Queen on her 90th birthday, it is also a story of inspiration and duty. We discover how the Queen supports her family in their public and private lives whilst continuing her official duties into her 10th decade. Interviews with Prince William, Prince Edward and his wife the Countess of Wessex by Sky's royal correspondent Rhiannon Mills were filmed on locations such as Kensington Palace. Viewers will also be following Her Majesty's numerous engagements over the past year.
