Gay British millionaires Tony and Barrie Drewitt-Barlow hit the headlines when their two children, Saffron and Aspen, were born to a surrogate mother in the US, using donor eggs and the couple's sperm. The pair were accused by some of 'going against nature' and 'shopping for the ultimate gay accessory'.

This intimate Cutting Edge documentary gets behind the headlines to paint a distinctive portrait of a unique family, and looks at how Tony and Barrie's single-minded determination to have children has affected them and their kids.
