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 Nazi invasion . . .
Duty Calls: Battle of Britain, throws you deep into the heart - and horror - of Britain's darkest, and finest, hour.
