Set in the year 2052, Earth has managed to find peace until the arrival of the Death Force – ruthless aliens from a dying solar system – who are desperately searching for a new home. Attacking the Earth with a massive satellite ship called Terror Star, the aliens proceed to terraform the planet to make it their own. For mankind there is one hope: it's up to Colin Collins and a small band of his fellow surviving students to crew a top-secret submersible vessel that can fight the invaders at sea or in space.
