With the fate of America hanging in the balance, Doc Savage and his fearless crew battle a hideously white-faced man named Ool who kills merely with a touch of his finger. The only clue to his diabolical power is a mysterious pair of dark goggles which brings death to whomever possesses them. The trail leads to a fabulous lost super-civilization hidden deep in the bowels of the earth, where Doc Savage and his fabulous five face their supreme challenge.
