Visually gorgeous film with an exotic soundtrack. Lina Romay has a good dual role where she is restrained as Doriana and uninhibited as her twin sister. The plot is reminiscent of Female Vampire with the whole death by sex motif but here, the sex is hardcore and a maybe bit too gynecological. Nevertheless, the film is sumptuous from start to end and makes for a relaxing watch.
One of Franco's rarest but best, Lina Romay gives a superb dual performance: once as the lonely rich title role, the other as her mentally ill twin sister. Beautifully shot and extermely erotic, it remains one of my four all-time favorites by Franco (which the first three are Soledad Miranda's last three). It's a shame that they haven't released more copies of this on DVD but still you can find it on amazon.
