[1] Captain Tom Forester is an American man from Cleveland, Ohio, who wants to become a pilot as his father (who fought in WWI against the Germans in the Lafayette Escadrille) as WWII begins.
During the training and their scout with their Hawker Hurricanes they find a formation of six Ju 88 German bombers, which are all downed by Forester before the arrival of three Me 109 German fighters, but they are all hit by Tom which go through the scout and finds two more Messerschmitt fighters: one is downed by Stone with an "Ace Kill" and Forester manages to do the same.
After the conquest of France, the No 79th Squadron is sent back to England, operating from Biggin Hill air base, south of London.
The next mission focus on another pilot: Captain Danny Miller, a British man from Liverpool who entered the RAF as the war began.
In his first mission, Miller has to intercept a flight of six Me 110 heavy fighters deployed as an escort for He 111 bombers which are going to arrive on the town of London to bomb it.
The third mission returns to Forester and Stone on the day of Adlertag, when the Luftwaffe bombed the British air bases: the duo are the only pilots able to take off and intercept the following waves of Heinkel He 111 bombers, shooting them down.
