In a grim future, Earth has been destroyed in a devastating alien attack and mankind is cast adrift, homeless in the galaxy. Young Cale, orphaned in the attack many years ago, is recruited (somewhat against his will) by Korso and his crew to find the legendary ship Titan which was built by Cale's father. The ship has the power to create a new home for mankind and Cale has the key to finding it literally in the palm of his hand.
