Synopsis by Hal Erickson
Zena Marshall guest stars as Tania, a beautiful scientist from behind the Iron Curtain. Hoping to defect to the West, Tania turns to "Invisible Man" Peter Brady for help, in exchange for assisting him in his efforts to become visible again. Alas, Tania's countrymen kidnap her and attempt to smuggle her back to the East in a coffin--forcing Brady once again to use his unique "gift" to foil the villains of the week. The episode's most memorable special effect is reserved for the end, wherein the unseen Brady commandeers a motorcycle.
