Im searching for the name of an old movie.!

I was watching the movie a couple of years ago!. It had a couple stranded and they came across an town!. It was a group of people and they were on trial!. I cant remember the plot, but in one scene a couple fell through the trap door which was a slide, the slide splits into two destinations which one was killed and the other landed in a pile of bones!. Could you help because I really want to watch that movie again!.Www@Enter-QA@Com
