The Space Guardians

AD 1999. A nuclear cataclysm has blasted the Moon and its Alpha base out of Earth's orbit, plunging it into the black gulf of deep space. With no hope of return, the Alphans were forced to wander through the star map in search of an hospitable planet.

They found Piri, a peaceful, lush world, a near paradise. Or was it?

To Commander John Koenig, Piri spelt danger - it was a mysterious planet of grey ash and blackened rock that had bewitched his crew. Hopelessly outnumbered, the base was evacuated to Piri and there Koenig discovered just what had taken control of their minds.
