Storyline:
Cataclysmic conditions on Earth forced a mass exodus to a distant planet. Generations later, a manned mission hurtles back to assess living conditions on the desolate, mostly submerged world. The sole survivor of the expedition is attacked by a violent band of scavengers, themselves locked in battle with a far more sinister foe. Now, mankind's very survival depends on the bravery and ingenuity of the lone astronaut.
