In a grim future where overpopulation and massive droughts have turned planet Earth into a barren wasteland, sex has been outlawed and the only place to find a little action is the Sex Galaxy. Hard-working astronauts Capt. Grayson (Anthony Jenkins), "Big" Ben Dorsett (Stephen Heiser), and Billy (Ben Phillips) have been recruited to patch up the plumbing on Space Station Six . After getting the job done in record time, they reckon they've got a little extra time to clean their own pipes. Rumor has it there's a distant planet inhabited exclusively by gorgeous amazons who live to satisfy men. It's the perfect place for a little R and R after a job well done. Upon arriving at their destination, the astronauts find that there are indeed legions of lusty females as far as the eye can see; unfortunately, they're all slaves to a tyrannical robot pimp named Wron, and enormous dinosaurs wander the land in constant search of a human snack. The first-ever "Green Movie," Sex Galaxy was assembled completely of public domain and stock footage.
