In a fictional world similar to our own, peace has broken down in Erusia, a small island in the continent of Eugea. Despite the country's size, Erusia's military arm has captured the capital of a neutral neighbor and taken control of "Stonehenge," an electromagnetic rail gun that can be used as a devastating anti-aircraft weapon.
An international coalition called the ISAF (Independent States Allied Force) is formed to try and counter the threat. You take on the role of their newest recruit - a young pilot seeking vengeance against the pilot that destroyed his home and killed his parents.
