Monster from Green Hell

“The mammoth monster that terrified the Earth! Too awesome to describe! Too terrifying to escape! Too powerful to stop!”

Dr. Quent Brady (Jim Davis) is an astrobiologist who sends wasps into space on a test rocket to study weightlessness and radiation, and then loses control of it. The rocket comes down in the jungles of Africa, so Brady and his partner Dan Morgan (Robert Griffin) mount an expedition to find it. Kenneth G. Crane sends them into a country where the wasps have grown huge, and Brady keeps pushing forward because the experiment is his.
