 After the death of many brides in their weddings and disappearance of their corpses, the snoopy journalist Patricia Hunter (Luana Walters) notes that all of them were wearing an orchid in their breasts. She finds that the hybridization of the orchid was made by Dr. Lorenz (Bela Lugosi), and she decides to interview him about the flowers. She hitchhikes on the road with Dr. Foster (Tristam Coffin) and they are hosted by Dr. Lorenz in his isolated house. Dr. Lorenz is indeed a mad scientist that sleeps with his wife in coffins, and with the assistance of a dwarf and his strong retarded brother, extract gland fluids from the neck of the abducted virgins to keep his elder wife young.
