A man who is feared in the area. Janet is afraid that her father's madness could affect her as well. Shortly afterwards, dead women with teir throat torn open are being found. Haunted by nightmares, Janet assumes that she is the killer...
The Original Version of the movie is less than 70 minutes long but in the mid-60s, the movie was prolonged for TV because a length of approx. 75 minutes was required. There are new opening and end credits plus two additional scenes. At least, the first additional scene is from the movie "Frankenstein 1970" - as the trailer shows - and Frankenstein became Dr. Jekyll. That scene does not really fit in the movie because later on, Janet sees herself as the killer in her nightmares. The second scene with Dr. Lomas being chased by the villagers is probably from that movie as well.
