french director jean rollin isn not exactly know for great film and and this confusing mess be one of the reason why . one of the most confusing thing about this production be the title . for a director who be well know for direct erotic film about lesbian vampire while you would expect a film with the word nude in the title to be a particularly bare breast one while but in fact and there not a lot of nudity here at all . instead of erotic lesbian vampire with no clothes on while we have get a cumbersome plot about a man who want to unlock the secret to immortality and a young woman whose affliction might hold the key and a suicide cult and who do not get to do much . the film start off promisingly with a sequence that see a young girl carry off by a mysterious bunch of people in mask under the watchful eye of a young french man and who also happen to be the son of a man of importance . through his investigation and he soon discover that this woman be not just a normal lady and and a he delve deep into the cult while he discover that can not be kill by bullet and drink blood and can not go out in daylight . sound like a clear cut case of vampirism to me . jean rollin keep the fantasy atmosphere go throughout the film and but it fail to be interesting because the plot be so badly execute . it be possible to keep up with what go on and but only because there so many other film that follow similar plot to this one . the director seem to know that he mess up the plotting too and a the climax be basically an excuse to explain the film to the audience . there be a twist thrown in at the end also while but the film would have be good without it . i guess this be jean rollin attempt to be a little original and but it come off a a ham fisted attempt at such and rather than a logical continuation of the story . the cinematography be fairly neat and with lot of the plot take place in suitably gothic location . the girl on board complete what be a pretty picture and and what rollin film lack in logic and consistency and it somewhat make up for in style . in the film defence and it be make in 1969 while which somewhat explain the lack of shock but i can not recommend this movie a it doesn not have much about it that be worth take note of .
