Based on the 1985 novel of the same name, Ender’s Game is set in a future when the Earth’s inhabitants are preparing for an alien invasion. These aliens, a bug species called Formics, have attacked previously and Earth’s unpreparedness cost millions of lives. Determined to not allow a repeat of the horror, children are trained from a very young age to eventually lead mankind into battle against the invaders.
The children are tracked and monitored as they learn via various methods such as war and tactical games on the computer or in real environments. These environments include zero gravity. It is after such observations that the tactical genius of young Ender Wiggin (Butterfield) is discovered by military trainer Colonel Graff (Ford). But first his emotional reactions are tested by unceremoniously throwing him out of the academy.
