This begins with a quote attributed to the Dead Sea Scrolls and ends with a quote from Poe's "The Imp of the Perverse."
In the opening scene, a woman goes to visit what seems to be a trailer park gypsy (in fact, a necromancer operating out of her garage). The woman is there to complain about something, asking for it to stop. The necromancer causes an axe to float up in the air and chop the woman. Something of the special effects budget and limitations becomes obvious when the axe's chopping is depicted by a closeup on the axe. That way, you can't see the crew member presumably holding the axe (they could handle having it float, but having it cop while floating - too tricky). Additionally, this saved them the trouble of having to show the woman being chopped. They just put some blood on the axe and kept her out of the frame.
Three college guys steal exams from a professor's office, and also find a letter from a student to a professor indicating she'd had an affair with him. She also happens to be working late that night, and they catch her. One rapes her, while another holds her, and the third watches. They threaten to go public with the letter if she tells.
The woman doesn't report them to the police both because she is worried about the consequences to her scholarship if her affair with a teacher is discovered, and also she doesn't want her boyfriend to know about the affair either. When a friend sees an ad for a revenge service, they go to the necromancer.
Revenge comes by way of a (seeming) doppelganger that appears like the woman to the men she wants revenge on (and even others she is angry at). Blood erupts from bathroom, the doppelganger emerges to start making out with the guy, nibbles on his shoulder, the eyes glow green, and then thick red demon hands appear and the guy dies.
There's also a guy named Ernest, wearing blue jeans torn at the knees, a red t-shirt with a black pentagram on it (only one point pointing up, though), hair dyed black with green highlights, and classic horn-rimmed nerd glasses. He's worried about what the necromancer will do to the woman who hired her, and tries to warn her and do ceremonies of his own to protect her.
The woman's professor also wants to restart their affair (while he is also working on adding other women to his conquests). He's less than average-looking, overweight, with a perm and mustache, but he still gets the women somehow. A drama teacher at my high school looked about the same and accomplished the same (somehow keeping his job after having been caught having one of those affairs, too).
When the woman realizes the guys who raped her are being killed, she is alarmed. For the rest, well watch it if you must, but it's not all that great of a movie. I saw it on videotape, and the dialog was hard to hear at times, although I understand the DVD's audio is fine.
Incredibly, the video box claims the movie is "A special-effects extravaganza in the tradition of 'The Serpent and the Rainbow.'" Yeah, right! There's not all that much by way of special effects, and what there is is pretty bad. When the demon of vengeance shows its face, you'll wish they hadn't bothered.
