Famine grips the world. Celestia has no choice but to take what the citizens of Equestria need to survive from other countries by force. She forms the Solar Empire. Whirlwind, a Pegasus from Cloudsdale and old friend of Rainbow Dash, decides to join the Solar Empire Air Force alongside Rainbow to fight for their country, friends and families.

But all does not go well. Whirlwind, now branded a traitor to the Empire and Equestria, finds himself on the run even though he was only following orders. Can he outrun the biggest and most powerful empire in the world's history, can he live with himself after what he had to do to his best and only friend and can he restore peace back to the world?
