When I see this title I automatically think of a lousy Shirley MacLaine movie, but instead we have a carelessly made girl/girl video lost in the mists of the not so fabulous '80s.
The opening has misspellings for words as simple as "dimension", as it tries to advance a Twilight Zone aspect for femme protagonists entering "the Lezbo Zone".
It's just an excuse for extremely tedious lesbian scenes in which attractive performers waste their time and of course the viewer's time. In-joke of Linda Shaw being named Tina and Tina Marie named Linda is merely insulting.
Basically it shows two aspiring models converted to lesbianism, resulting in some very mild domination footage and anal sex involving toys (probably provided by that monopolist Doc Johnson).
The punchline hammers home the basic insult behind all of these male-made "lesbian" features: the heroines, now converted, have their sex scene shown on TV, watched by an old coot, who tips his glass towards the camera to salute all of us fellow dirty old men who view this crap.
