Hans Holbein, long recognised as the father of British painting, is an artistic enigma, wrapped up in historical myth and nationalist hyperbole. Holbein, so the story goes, was a child prodigy, who famously branded Henry VIII, painted his courtiers and then his brides and spied for his ministers, before ending his life in debt. But how much of this is true?

In this film, Alan Yentob goes in search of the real Hans Holbein. It's a detective trail that takes him to Basel in Switzerland, where Holbein spent his early years, as well as across the length and breadth of Britain. Alan employs the tools and science of the detective, beginning with a magnifying glass and ending in the reconstruction of the scene of Holbein's greatest exploit. Holbein's most famous painting The Ambassadors is recreated as a contemporary photograph by the renowned White Cube photographer Tom Hunter.

Alan Yentob journeys into the world wide web to find out how it began, who's out there, and where it's taking us. He meets Tim Berners Lee, the inventor of the web, and explores how Lee's creativity has fuelledthe creativity of millions of others - such as Dandy blogger Dickon Edwards and sex blogger Abby Lee, the hardcore members of the Arctic Monkeys message board, masked animator David Firth, and Ewan Macdonald, the young Scot who wrote the millionth entry in Wikipedia.
