Angela, a university student and social activist, is trying to start a protest group to stop the spread of nuclear weapons to the planet Mars before it becomes colonized. Meanwhile, a strangely-dressed man and woman are stalking her. Who are they? Where do they come from? What do they want?
It's the end of the century and Earth is dying due to global warming, overpopulation etc. A new planet is needed for people to live on and Mars is not big enough to accomodate the excess population. A new planet has to be found elsewhere but all known planets have aliens. As our hero Captain Dale says, "Good luck in trying to find a planet where the aliens are not stupid, cruel or rude".
