This is director Terence Fisher's ultimate statement of his unusual and deductive aesthetic and it embodies the very best efforts of Hammer Films' technicians and artisans. It's about one of those remote castles in some indistinct hollow of middle Europe. There, a handsome, young Baron is kept chained up by his mother who lives in fear of him. A lovely visiting schoolteacher is not afraid of him at all of course, so she turns the key to release him, which turns out to be a big mistake. Featuring the incomparable Peter Cushing as the vampire hunter. Thrilling, beautiful and a little kinky naturally.
