Blood of Dracula

Nancy Perkins (Sandra Harrison) is a sweet but perturbed teenager who is sent to a girls boarding school for guidance. There she unwittingly becomes the subject of a monstrous experiment -- at the hands of teacher Miss Branding (Louise Lewis) -- that blends modern hypnosis techniques with ancient black magic. This twisted process turns Nancy's confused and burgeoning feelings into an insatiable bloodlust, transforming her into a vicious vampire who remembers nothing when back in human form.
