St. Agatha

Most of the crew believed that the basement was haunted. The basement was actually an abandoned old morgue.

When Mary/Agatha is going through Mother Superior's desk she happens upon a stack of money. At the top of the stack is a modern $100 bill with the enlarged face of Benjamin Franklin. These bills were not put into circulation until 1996, which is, at the very minimum 40 years after this film is said to have taken place.
