Sprog: a rookie airman, forced to learn by doing.

Summer, 1941. They come from different places, and different lives, but they share a dream: to fly. Eager to join the war in the skies over Europe, thousands of young men flock to Canada from all over Britain and the Commonwealth, and the United States - all hoping to earn their pilots' wings. Before taking to the air, they must endure the challenges of the British Air Commonwealth Training Plan, which quickly turns them from boys into men, and from civilians into soldiers. Sprog takes us from Bomber Command's war, to the retreat from France, and to the peaceful but dangerous skies of Canada where these young men will discover themselves, and their destinies.
