A huge burrowing machine tunnels out of control at ferocious speed, cutting clean through to the center of the earth, to the twilight world of pellucidar. Once there, Dr. Perry (Peter Cushing) and David Innes (Doug McClure), are threatened by half human creatures, lizard-like birds, and man-eating plants.
