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.
