Name That Trauma:: Steel Jaw on a Satanic Cult

Hi there once again Kindertrauma,

In the past you guys helped me out finding movies of which I forgot the name. I hope you can help me out with this one too.

So I saw this movie many years ago at the BBC-channel. It was a seventies horror movie, I believe it was a British one. The movie was about a satanic cult. In the opening scene there was some kind of sacrificial ritual at night on the beach. The people who were involved in the cult wore goat-like masks. I believe they were sacrificing a young woman, presumably a virgin…

A bit further in the movie we see someone (can't remember if it was a man or a woman) staying over at the house of a family member. The person who stays over is fearful of the person who lives there (also could be fearful of a supernatural force).

Later on in the movie there is a couple that want to warn the person in the house. When driving over to the house they have a car accident, what I believe is being caused by someone with supernatural powers, giving the driver some kind of stroke. They crash into the stone fence.

I'm not sure, but it could also be that there are vampires involved in this movie (not so sure though).

I really hope you guys can help me out with this one ??

Cheers!
