The on-screen title is actually "Weekend Fantasies" -- not that that changes anything.
This is a mean-spirited porner about a bunch of losers, led by creepily believable porn veteran Bill Margold, who get together each month to use and brutalize various willing women. When they get bored, Margold sees a porn actress in a video (Kathy Konners) and decides to kidnap her and use her as a sex receptacle.
It's not an inspired idea and the execution by director Joe Luchine is by-the-numbers.
Ms. Konners ends up being tossed into a chicken coop and orally raped by the sincerely misogynistic Margold. There are snatches (pardon the pun) of eroticism and a climax featuring some feeble demonic imagery during a mildly intense orgy.
Of interest, Armand Weston's much better THE DEFIANCE is discussed by a character in the movie and screened on a TV. And the soundtrack is occasionally livened up by a moody cut from Pink Floyd's "Dark Side of the Moon" LP. I'd bet a night with a porn actress that Floyd received no payola for their appearance in this class act.
