Bela Lugosi revels in his role as European horticulturalist Dr. Lorenz in this outlandish tale of horror and dementia. The good doctor's aging wife (Elizabeth Russell) needs fluids harvested from the glands of young virgins in order to retain her eternal youth and beauty. What better place for the doctor to maintain his supply than at the alter, where he kidnaps the unsuspecting brides before they can complete their vows. Sedating them into a coma-like state he brings them to his mansion to collect his tainted bounty.
