Need help with movie memories!

I remember this movie from when I was a kid. It seemed really weird and I didn't understand it, but then again it was the 70's! Any help anyone could give me would be very much appreciated.

Something about a ring that once put on, couldn't be taken off. There were allot of people in a big old house, maybe a dinner party? I remember a part about a man either falling out of a window or being pushed and attack dogs below. There was also some old woman that was on her death bed in the house, and the bed had ( I think) plastic drapes around the bed, possibly to keep out germs. Then some of the people tried to get away from the house and drove away, but all the roads seemed to lead back to the house.

This is pretty much all I can remember, so if any of it rings a bell, please let me know!

If you posted this in the right section you'd be more apt to get a reply.

Take a look at the description for this part of the forum: "...from the 1960's and before". You're looking for a "Modern" horror movie, so you'd have more luck in that part of the forum.Douchebag

Im probably wrong on this one, but for some reason your description vaguely reminded me of this one:

http://www.imdb.com/title/tt0079450/

I think that's it!! You are amazing. Thank you very much for the end to a very long quest.

Aw, thanks. I do hope that is the one you are looking for!

the link is correct - it's The Legacy.

(it was an old man though - not an old woman)
