La señorita Gray, una aristócrata solitaria, tiene una hermana gemela que está en un manicomio.
Comparten un vínculo extraño.
La señorita Grey es racional pero frígida, mientras que su hermana está loca pero siente placer sexual por ambos.
This film, as other reviewers have noted, is pretty much a remake of "Female Vampire" from a few years before. What's amazing is that the non-sexual scenes are actually more erotic than the porn scenes are.
DORIANA GREY is another worthless pornographic outing from cult director Jess Franco, here shooting in Switzerland with the aid of his mainstay wife and actress Lina Romay. This is essentially another version of the FEMALE VAMPIRE story, with Romay playing the dual role of a woman and her evil twin who literally sucks the lifeblood out of her victims.
Lina Romay is stunning in a dual role here, in an atmospheric hardcore feature loosely inspired by "The Picture of Dorian Gray". Her principal role is that of "Doriana" Gray, a mysterious young lesbian living in a secluded castle.
