Justine is a tall redhead with milky-white flesh who has a hard time keeping her naughty hands off of her horny pussy. Therefore, her Master (Karl Kagan) loans her to the sinister Bruce Payne in the hope that he might be able to get her to behave. "The only way you can learn is through proper pain," he tells her. (Same thing with studying Latin, by the way.)
Payne - this guy is really evil (he actually bears long, sharp fangs for canine teeth) - goes out of his way to put Justine through her paces. It would actually be easier to name the cruel things he doesn't do to her and the tools of pain and pleasure he doesn't use, but let's try to list a few anyhow. Some highlights: teasing, spanking and whipping Justine with a hairbrush, a wire paddle, cat o' nine tails and something that looks like a rainbow-colored feather duster. He then proceeds to drag a letter opener over her skin and near her vagina. Her wrists, knees and ankles are bound with rope, leather cuffs and a metal chain and clothespins and hot wax put on her nipples, clit and tongue. She does quite a bit of yelling and shrieking, not surprisingly. "Tell Daddy how it hurts," he says.
Another notable moment is when Payne allows Justine to rub her pussy to a powerful, squirting O.
In the final scene, as Justine sits on a gynecological table, Payne pierces her nipples and abdomen with needles. He then pierces her labia and, with red thread, sews them together. Incidentally, he also decides not to return Justine to her (former) Master.
Couple of not-so-great things, however: The quality of the videotape isn't the greatest and the editor really should've eliminated the bits where the director instructs the performers.
Oh, and one additional positive: cool music.
