The movie starts with a woman in a thin white robe being placed on an alter by men in black robes. An older fellow starts groping and licking her. This had nothing to do with the movie.

A couple are driving and another couple wave them down and the driver says the other drivers name. He said they went to school together. He has zero memory of the guy but goes an hour out of his way to have cheese and wine at his house. Ouija table gets put into use. Satan is around. Orgy. A dog is killed. WTF?!?

That said, it wasn't a total dud. It had a creepy/erotic vibe that only the 70's could produce. Fair amount of nudity. Honestly while I watched I thought it had a cohesive plot. It's shaky at best.
