In the skies over the world devastated by the First World War, young eagles fight with a chivalrous spirit. Below them the great war is being fought in cold and terrible trenches by the Central Empires and the Allies of the Entente. While thousands of men lose their lives on land and sea in a cruel and merciless war that covers no man's land with death, brave airmen fight with a sense of honour and respect for their adversary. Everyone is convinced that they are doing their duty, in the name of their ideals and for their country.
