Synopsis
In the year 2052, Earth is enjoying a period of global peace. However, this tranquility is shattered by the arrival of the Death Force, a hostile alien race.
These aliens, hailing from a dying solar system, are seeking a new planet to call home and they've set their sights on Earth.
Using a massive satellite called Terror Star, the Death Force begins to terraform Earth, making it suitable for their own survival, threatening humanity's existence.
Mankind's last hope rests on a group of students, led by Colin Collins. They must pilot a highly advanced submersible vessel, capable of operating both in the ocean and in space, to defend Earth against the alien invasion.
