This film explores the events of September 15th, 1940 - the day Churchill described as the 'crux of the battle.' On a day now celebrated as Battle of Britain Day, Adolph Hitler's Nazi war planes fought the British Royal Air Force. Dramatic color film footage of aerial combat combined with contemporary interviews show the power of events seventy years ago to resonate down through the generations.
