The Ultimate Vampire Resource and Directory

Count Ludwig von Karnstein (Christopher Lee) lives under a fearful curse placed by one of his ancestors before she was executed as a witch, stating one of her descendants will be her diabolical reincarnation. While Ludwig attempts to locate the evil ancestor's hidden tomb, a series of horrific vampire killings erupts in the castle -- and the culprit might be Ludwig's own daughter. Chilling and atmospheric, this adaptation of J. Sheridan Le Fanu's horror classic Carmilla was also released as Terror in the Crypt.
