On a dangerous future Earth filled with monsters, an orphan tries to escape back to SkyArk, a man-made city in the sky, but he soon learns that he has a much greater purpose.

One thousand years after cataclysmic events forced humanity's escape from Earth, Nova Prime has become mankind's new home. Legendary General Cypher Raige returns from an extended tour of duty to his estranged family, ready to be a father to his 13-year-old son, Kitai. When an asteroid storm damages Cypher and Kitai's craft, they crash-land on a now unfamiliar and dangerous Earth. As his father lies dying in the cockpit, Kitai must trek across the hostile terrain to recover their rescue beacon. His whole life, Kitai has wanted nothing more than to be a soldier like his father. Today, he gets his chance.
