Edward III rips up the medieval rule book and crushes the flower of French knighthood at the Battle of Crecy with his low-born archers. His son, the Black Prince, conducts a campaign of terror, helping to bring France to her knees.
England, wracked by plague and revolt, loses the upper hand until Henry V, determined to prove his right to be king, turns the tide at the battle of Agincourt.
Henry V has claimed the French crown for his heirs, but to secure it the English must conquer all of France. Potent French resistance comes in the most unlikely form of an illiterate, young peasant girl - Joan of Arc.
