 During the 15 episodes, Holt endures numerous brushes with death, emerging from all of them with nary a hair out of place nor a crease in his well-tailored business suit.In this serial, Jack Holt strictly played himself with all the gimmicks he had used at silent and talkie movies still very much in evidence.Producer Larry Darmour felt the serial was made for adults and not children by making it thrilling and logical but never impossible.
