A brilliant scientist by the name of "Professor Greaves" (Nerio Bernardi) has just invented a serum that rejuvenates cells and reverses the aging process. His assistant, "Dr. Marny Bannister" (Magda Konopka) desperately wants the formula due to the fact that she is scarred and ugly. However, Professor Greaves is cautious and wants to do more research before even attempting to try it out on a human being. Dr. Bannister then kills Professor Greaves and ingests the serum which turns her into the young and beautiful woman she always wanted to be. But there are two important factors which Dr. Bannister failed to take into account. First, the formula unleashes savage and primordial desires into whoever takes it. The second factor is that the serum wears off after a period of time and the person reverts back to their previous form. What follows is a murderous rampage by Dr. Bannister who is not averse to using her beauty to further her evil desires. Although it was originally filmed in Italian, the English dubbing was very noticeable. Also quite noticeable was the fact that a scene or two was cut rather abruptly. This gave the film a kind of choppy feel. Still, Magda Konopka looked great and the film had a nice late-60's atmosphere to it. All things considered I give it an average rating.
