To save many, he'll sacrifice a few. Missing for ten years, Dr. Leon Kravaal (Boris Karloff) has been found! Frozen solid in a block of ice, Kravaal was conducting forbidden experiments in human cryogenics when he became trapped within his own freezer. Thawed out by Tim Morgan (Roger Pryor) and Judy Blair (Jo Ann Sayers), Kravaal vows to continue his research, using his enemies as guinea pigs. But with the death of his last human "volunteer," Kravaal decides it's time for Time and Judy to sacrifice their lives for science, in this chilling tale of cold-blooded murder.
Boris Karloff performs in one of his specialty roles, in the second of Columbia's "Mad Doctor" series. Nearing the completion of his cure for cancer, Karloff's research requires that he freeze the subjects he is attempting to cure, and administer the medicine while they are in a suspended state. Unfortunately, he is accidentally frozen along with his patients, only to be discovered by another young scientist many years later. Once he and his patients are revived--by hilariously low-tech means--the doctor is distressed to find that his hard-won medical breakthrough has been lost. Desperate to rediscover his cure, he resorts to murdering his thawed-out patients, and spirals further and further into madness.
