The cast and creators of the award-winning drama series tell the story of the show from the inside. The actors talk exclusively about their characters and the gripping storylines, giving the audience a real insight into the romance and conflict portrayed in the series. There is also behind-the-scenes footage from key locations - the historic Ealing Studios in London where the 'below stairs' scenes are shot and the fabulous Highclere Castle in Berkshire, site of most of the 'above stairs' scenes. Plus there is a look at the filming of the dramatic opening of the second series, set during the Battle of the Somme and shot on location near Ipswich.
