Country: Italy - Belgium
Six of seven tourists in a east European castle overnight are victims of a helper of the devil. Is Satan willing to spare their souls? Erika Blanc is perfect as Lisa Miller, the succubus. She displays supreme sensuality in her "normal" guise, then transforms into a murderous demon with such face-pulling, over-the-top relish that your skin will crawl. If she's not enough, Daniel Emilfork is on hand to complete things as a corpse-like vision of the devil. The deaths are creative and brutal, the Gothic castle is very creepy, and the ending has a shock-twist that you'll never see coming.
