Ender Wiggin (Asa Butterfield) is a teenager on a very important mission - to save the world from annihilation.
Fifty years previously, an invasion by the Formics, a genocidal alien race, nearly saw the end of the Earth.
Only the brave efforts of Mazer Rackham (Ben Kingsley) saw the invasion fleet destroyed and the world returned to safety.
But Colonel Graff (Harrison Ford) wants to ensure the Formics cannot rebuild and stage another attack.
He knows the future of the human race lies with the exceptional young minds of tomorrow's adults who are able to lead their military into battle.
