I might have a couple movies confused. I looked at the youtube clip and thats not the movie.I want to say it has a trap in the floor and the bad guy is trying to get people to sit in the chair. When they do, the chair flips backwards and they fall into an underground cavern. I am pretty sure no gets killed except the woman. The bad guy is after her estate maybe? I looked at some of the movies Mantan Mooreland because I was thinking he was one of the people that actually falls into the trap but finds a boat and rows out of the underground cavern.
The woman ghost is trying to find out why sh
