Its a B grade movie with low profile actors.. a sexual predator kills the girls to fulfill his ambitions. Good for One time watch only.

I don't want to give away too much but we do know that Herbert murders a girl at the beginning of both versions and after that it is a bit of a cat and mouse with the cops who are trying to solve the murders along with Herbert who is a criminal psychologists and suposed to be helping them in the investigation. His wife starts having weird S&M dreams invloving her husband as the sadist and their maid and another woman who we later find out is her niece. Ther three women fondle and kiss each other while Herebert watches. The editing from the dreams to reality is a bit confusing and at one point early in the film Herbert does beat and cut Marcia as a substitution for sex which he can't perform with his wife. He does seem troubled about his violent tendencies and does not want to unleash his murderous ways on his wife. But he does like looking at her throat which is a very enticing part of female anatomy for him.

It was okay for a '70s flick. It was obviously the cut version. I would be interested to find the uncut version.

This isnt in English....subs though
