A randy archeologist, his naïve assistant, his lusty wife, and her longtime lover all discover just how much fun can be had while searching for ancient civilizations in director Joe Sarno's classic sex romp. Archeologist Walter has brought his wife Laura and sultry assistant Anna to a small island off the Swedish coast in order to search for traces of a long-disappeared civilization that once settled in the area. Though at first Walter and his assistant make little progress in unearthing clues to the fate of the mysterious civilization, it doesn't take long for the pair to realize that it's far more fun to wade between the sheets that on the beach. When Laura sees just how well her husband has gotten to know his beautiful assistant, her initial anger soon gives way to a lust that becomes difficult to maintain. Back in her schooldays, Laura and her classmate Hanni explored every conceivable pleasure together, and as fate would have it Hanni is currently visiting the mainland. After making contact with her longtime friend and lover and subsequently becoming infatuated with the buxom Anna, Laura becomes convinced that it is her mission to school the buttoned-down archeologist-in-training in the fine art of forbidden female pleasure.
