The brilliant detective Hammer, along with his beautiful wife Mary, have been assigned to investigate reports of a monster sighting at the local nudist colony. Not an adventurous couple, they would never think of visiting such a place. Once they arrive, however, Mary loses all inhibitions and realizes she can mix business with pleasure. Detective Hammer is a little more reserved, but slowly distracted by Lucy, the nudist colony’s manager, he, too, decides to bare all.
