An old rich actress name Ruth Warren finances a scientist named Gregory to create a serum to help her obtain her youth again, so she can receive more acting roles. However she doesn't know that he has been using the brains from cadavers in order to create the serum, and that is the only way that she can keep her youthful appearance. Ruth's dependence on the serum causes her to crave more, and turns her into a murderous monster.
