Curvaceous cult actress Joi Lansing appears in this episode as policewoman Helen O'Hara, who upon meeting Superman (George Reeves) evidently exudes such an attraction that the Man of Steel instantly proposes marriage! This of course is all part of a scheme to bring elusive criminal mastermind Mr. X (John Eldredge) out in the open to attempt the kidnapping of "Mrs. Superman"--whereupon the police will slap the cuffs on the villain. Unfortunately, Mr. X not only manages to abduct Helen and bind her to a bundle of sputtering explosives, but he also seals Perry (John Hamilton), Lois (Noel Neill) and Jimmy (Jack Larson) in a leaky diving bell some 250 feet beneath the sea--and though he may be able to bend steel in his bare hands and change the course of mighty rivers, no way can Superman be in two places at once!
