Those bloody teenagers and their psychic abilities! You do your best, invite them to stay when their mum dies, and what do they do? Start glaring at things evilly, rub toast on the maid's face, and cause a local doctor to miss his mouth when drinking water.
The girl is Letizia and she looks about as much like a teenager as I look like Beyonce, but let's go with the flow. She arrives at the villa of her Aunt Michela and her husband Gabriele Tinti, and although things start out simple enough, it becomes clear that something is a bit strange about Letizia. First, she comes on to the butler, but at the same time scares the crap out of him by transforming into some sort of demonic Bee-Gee! This affects his sex-life with maid Gassella, who Letizia also comes on to (with some erotic toast rubbing), which somehow causes Gassella to come on to the Aunt. The Aunt resists, but someone is hiding and taking pictures of the naughty deed!
Gabriele and the Aunt also take Letizia out for some dinner where they are met by a psychologist (turns out the Aunt has been having some sort of funny turns and may have had a breakdown in the past). Letizia gives him the evil eye, which makes the psychologist simply pour the water down the side of his face. Yes, Letizia has some sort of evil power, but what does she want with the family, and who is that guy hanging around the place, looking sinister?
What we have here is the plot of a late sixties giallo with a pinch of the Exorcist thrown in because this film was made in 1975. There's also a lot of nudity, and Gabriele Tinti gets to sleep with every female in the cast. You get a lot of dodgy visual effects as Letizia walks through walls etc, and a nihilistic ending that's pure seventies gold. Too much screaming though, way too much screaming.
