A shape-shifting space alien takes the form of a handsome young man on Earth and, after violently doing what he was sent for (which we learn at the end), he finds two pretty lesbians holed-up in a rural country estate... just so he can study their daily/nightly routine... Which means that men are all the same no matter what planet they derive...
For a robotic-like Barry Stokes it's a complicated (and often risky) lesson of love and jealousy in what's an offbeat triangle within a low-budget science-fiction horror, with plenty of intended downtime...
Giving the feel that cult director Norman J. Warren's PREY is actually more of a deliberately slow-paced arthouse thriller, and, filmed in England with British actors, the acting's quite good when it really shouldn't be...
Featuring the more feminine and once straight Glory Annen (with an unseen backstory involving an ex-husband), who's given either loving/controlling kisses or dirty/frustrated looks by her shorter-haired yet equally attractive Sally Faulkner, the most fun is how the bickering couple tries figuring out this strange male visitor, who winds up like a benign, manipulated little brother of sorts...
Meanwhile the taboo exploitation gets sporadically intruded upon by what hardcore horror fans want much more of, like gruesome body count deaths by the alien, particularly while sporting full fangs, an interstellar wolfman, who, despite having plenty to watch (as a voyeur along with the intended male audience) has very little to do.
