Journalist John Sergeant joins Sophie Raworth and former Army Officer Andy Torbet at the Imperial War Museum at Duxford in Cambridgeshire. The site was an important airbase during the Battle of Britain and John has a fascination with the heroic men and women who risked their lives in the skies. Former 'Spitfire Girl' Joy Lofthouse reminisces about her service delivering fighter planes to the frontline and flies a Tiger Moth at the age of 92. Veterans read the inspirational words of Churchill's wartime speeches and Andy meets a woman who worked in a Battle of Britain operations room. There is also a performance of an iconic World War Two song by The Three Belles.
