Wednesday 24 July 1940.

Pilot Officer Archie Jackson, 19, is in control of the RAF’s newest fighter aircraft, a Supermarine Spitfire.

Now he has the Luftwaffe in his sights and only one thing matters: defending Britain.

Suddenly planes are falling from the sky, exploding and spiralling into the English Channel.

France has fallen and the swastika flies over occupied Europe. Only these young pilots—barely out of boyhood—stand between Britain and a German invasion in the summer of 1940.
