Ok, scratch the Vatican. But this dungeon was definitely underground somewhere. Maybe it was in Mexico. I'm having a hard time tonight.

I was just at the old forum site looking through posts that had anything to do with exorcism. Didn't find squat. Then I'm at this website called bestsimilar.com where you can find movies by genre. No luck there either. I'm about to Google search next.

I think the main story about this movie I'm trying to remember is about a priest or team of people that do exorcisms.
