The Earth year is 2020. Alien space ships approach the planet Mars. The Androids have journeyed from the planet Guk in the galaxy of Alpha Centauri and now their witch-like commander "Zelda" sets up her base on Mars and lays her plans for the invasion of Earth and the destruction of the human race. Alerted by the 1st Alien Attack in 2017, the UN High Commands appoint Dr "Tigger" Ninestein to devise and establish an elite international fighting force to defend the world against the unknown aggressors. This small dedicated team is called the "TERRAHAWKS". From their secret base somewhere in South America they develop their sophisticated weaponry and prepare for the battle to come.
