Raige is disappointed in his son, Kitai (Jaden Smith), whose application to join his father's Rangers is turned down. General Cypher Raige (Will Smith) is a "ghost", a soldier who has trained himself never to experience fear, thus making him an invaluable asset in the war against these beasts. These aliens, known as the S'krell, use a species of aggressive beast, the Ursa, which senses the pheromones released when a human feels fear. Mankind establishes a new home on a world called Nova Prime but an alien race also has designs on conquering the planet. In the future, Earth is abandoned by humans, thus becoming inhospitable.
