In After Earth (Columbia), 1,000 years after we destroyed the paradise that was our home, the planet is uninhabitable, overrun by species that have evolved to kill humans. General Cypher Raige (Smith) and his teenage Kitai (Jaden Smith), are dealing with an evolution on a more personal level. Described by his mother Faia (Sophie Okenodo) as a "feeling and intuitive boy," Kitai, who, in spite of having impressive test scores, is not promoted from Cadet to prestigious Ranger. He worries about disappointing his legendary father and is also still mourning the death of older sister Senshi (Zoe Kravitz), killed by an Ursa (alien). Meanwhile Cypher, who rose to prominence for his "ghosting" (fearlessness) skills, is aware of the chasm between him and his son and plans to retire following one last mission.
Encouraged by Faia, Cypher takes Kitai on the mission with him, to "make good memories together." But a brutal meteor storm seriously damages the ship in which they are traveling, causing it to crash on Earth, killing the entire crew with the exception of the father and son. Cypher, who is badly injured (two broken legs), sends Kitai out to track down a beacon necessary to facilitate their rescue.
From there the movie takes off in a couple of directions. One is an exploration of the relationship between father and son. Kitai feels like he has something to prove to Cypher and often disobeys him, putting himself in danger to do so. Cypher, on the other hand, has a military attitude about being disobeyed, especially by his own son. The other direction the movie takes is one of thrills and chills and special effects galore. Giant birds, killer feline hybrids, flying snakes and a ruthless Ursa make Kitai's journey a nearly impossible one.
