BDSM. For devotees of the B&D Pleasures production company, of course. The light electrical torture might be a selling point, also.
Here's the plot according to the box cover: "When a curvy detective is found sneaking around the slave pens of Marc Wolfe, it is a downhill trip to torture!"
Well, look, these things are seldom truly believable. The rubenesque Jacqueline Zamora as a detective isn't convincing, of course, but let's talk action.
Here's some of what mean Marc Wolfe inflicts upon Zamora: sharp cracks on the ass with a leather paddle, a ball gag, beating and slapping of the tits, whipping her back and hind-quarters with a cat o' nine tails and electric shock on her nipples. (The electric current is delivered through some type of wired rubber gloves.)
Later, Wolfe has a bound slavegirl kneel before Zamora and eat her pussy. Further tortures include nipple clamps, pussy clamps and caning.
Finally, Zamora herself gets the opportunity to use a riding crop and hot wax on sexy Erin Pearl. The wax really gets Pearl goin'.
This tape doesn't have the best sound, so consequently some of the dialogue is unclear. On the plus side, the editing keeps the pace of things moving along.
