L'Abîme de l'Enfer

Pretty grim film with a lot of equally grim atmosphere in a monastery somewhere, I presume, in Poland since it's Polish film. I was about to say the premise is, but this has a few premises so let me just say it's starts off with a priest shot to death while about to stab to death an infant thinking it to be the anti-Christ, very reminiscent of The Omen, and he might be right. We immediately switch to 30 years later when a detective infiltrates this monastery due to the disappearance of a number of women who went in only to never come out. It annoyed me for a while at how easily he discovers various things in his snooping around. He gets found out quickly enough and things get ugly and brutal and very gruesome. This is not a great movie, but it accomplishes what it sets out to do right to the end with no holds barred.
