Scotty Fox was a prolfic VHS pornographer, often making successful comedy, but this Vivid Video is just awful.
Tamara Lee stars and narrates (first 10 minutes play as a silent movie pantomime with her voice-over carrying the plot entirely) as she becomes invisible after getting chemicals on her hands, left behind by chem classmate Randy West. Initially the invisible effect ludicrously consists of her sweater sleeve down over her hand as if the hand is gone!
Things don't improve when dialogue begins, and often the invisible girl is represented by a reaction shot of an empty wall or piece of furniture. Tamara is represented by a first-person camera moving along, and her back & forth becoming visible shots have a crude special effect like amateurish imitating of Star Trek's "beam me up".
She becomes a voyeuse, masturbating as she watches folks make love, and visible when aroused. Rest of the cast provides more of that big-boobs content that Lee's big naturals yield for the horny home viewer.
Oddly, previous reviewer in IMDb rambles on endlessly about the movie's shots of women's feet, which made him a foot fetish. This is completely untrue, as the video does not include a single female foot closeup and none of the trademark "wide-angle" foot fetish shots that permeate thousands of porn releases devoted to that kink. This is obviously a breast fancier's video, period.
