A spacecraft captain and its pilot, Korso and Akima, two humans, seek out Cale, the youthful son of the dead scientist and explain that he must help them find the Titan, which holds a mechanism to unite and save humanity. Cale refuses, but the arrival of the killer aliens persuades him to join Korso. Can he avoid his pursuers, know friend from foe, find the Titan, and embrace his humanity, a nature he has despised until now?
