Well, usually Argentina puts out some quality creative drama, but this time - ughhh! Still another demon possession - a been done too-many-times-before script.
1. Usual person wearing a goat's head.
2. Usual CGI or contact lenses - blue eyes if kinda good; red if a real baddie. Usual fake scary demonic teeth for demon possessed.
3. Usual demonic voices in the background or growling demonic voice from the possessed.
4. Usual old big house in a secluded environment.
5. Usual lots of insects - big cockroaches here; also found in the usual strange opening in closet, of course.
6. Usual old garden w/strange tree and sculptures; next to cemetery w/more sculptures.
7. Usual semi-dead ghostly women jumping closer to our innocent nun.
8. Usual lots of lit candles surrounding our future victims; pentagrams on floor or body. To be Argentinian they have an indigenous, face painted, shaman with drumming & chants.
9. Usual pregnant (by whom we wonder) women w/usual upcoming child sacrifice.
Conclusion: About the only thing scary is seeing fake colored eyes & teeth for a few minutes other than that a few people are toast, but we don't see it happen. Film mentions Mahonin, a late 1500s name (given by Catholic exorcists) for a demon possessing a French women.
