A higher degree of terror!
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 Tim and Judy to sacrifice their lives for science, in this chilling tale of cold-blooded murder.
