My wife claims we watched a movie in about 2010…not sure how old it was by then..but not too old…it was definitely done in the 2000’s maybe even later 2000’s….but it is a horror movie….she says people went in to a cave and found some type of artifact or something like that and I guess they unleashed a demon or something….and people were getting possessed and stuff like that…and then they go back to the cave in the end or something and try to fix it…or it turns out it wasn’t really a demon it was just an evil angel killing people……and they thought they saved the world but when they left the cave they were wrong…..that’s really all the details she claims….I can’t go d anything at all online about it…..any help would be great thanks.
