In the final instalment, all four of the Queen's children talk frankly for the first time about their working roles as part of the Royal Family. The younger generation are also seen to be getting involved. There's an early-morning surprise for the residents of an inner-city hostel when they come down to breakfast and find Prince William making the coffee. Prince Harry attends a strategy meeting for his African charity, Sentebale. And we see what happens when all the family turn up for a very proud moment at Sandhurst.
