V: The Hot One (1978)

Sinopsis

Starring the stunning Annette Haven as V, the film follows her transition from housewife to a successful young attorney to high-priced call girl, to cheap street whore. From the penthouses, the Mercedes, the minks and the sparkling dinner parties, dingy skid row hotel rooms, V and her companions lead us through every facet of sensual perversion. You'll follow her from her home to a penthouse filled with 12 couples engaged in an elaborate orgy, to a stylish brothel for discreet millionares, and finally to a cheap hotel where anything with anybody goes.
