Tiffany Shepis, for some reason, travels to a convent in Italy at the behest of an American bishop. She wants to lead a religious life of silent contemplation. Instead, nuns dressed in red and their drunken doctor/slave make her deaf, blind, mute and boil her hands while they're at it. But she's, for some reason never explained even a little, in some sort of psychic contact with the aforementioned Ninfa and her crazy father/grandfather who, just because he's really crazy, does things like cut off his own leg and keep piles of dead animals in his attic. Ninfa and Tiffany are super, super scared of that. And thereby hangs a... tale?
No, a mess. Nothing here makes sense and the ending is a HUGE let-down after all the build-up. Other people's repressed memories just aren't that scary when you've been led to expect something supernaturally horrible by every clue in a film. It plays like director Ivan Zuccon simply didn't know where he was going at any point in this awful mess, so he just decided to run the whole thing into a wall in the end.
This could have been a perfectly good nunsploitation film, or a good horror film, or a fine drama. But it isn't any of those things because it never commits to any of them. Punt this one.
