The keywords list here gives away the only surprise in this ORGY movie: a cornball ending card that reads "THE END?" Otherwise it's just more or less what the narrator announces: a "real-life" orgy. (About as real as Reality TV, I guess.)
A pirated Tijuana Brass LP is used as the soundtrack, as we watch folks hump in a little club with a bar setup, including bartender and waitress, who join in as well. Some folks dance when they aren't coupling, and the sex is mainly soft-core with some XXX thrown in. A new arrival looks like James Franco -fortunately for his resume he wasn't born yet.
Movie was shot MOS, with moaning and adult baby-talk dubbed in. If you're wondering why such drivel still exists 40 years later it's because Something Weird issued its cache of movies randomly when compiling a sort of history (or snapshot at liquidation) of the Dragon Art Theatre.
