In the conclusion of a two-part story, Inspector Erskine (Efrem Zimbalist Jr.) has learned that defecting East European cryptographer Holman (George Voskovec), reported killed in a fire, is alive and in hiding from his countrymen. Assisted by Holman's wife Barbara (Dana Wynter), Erskine goes to great lengths to convince Red diplomat Korvin (Paul Lukas) that Holman is indeed dead. Meanwhile, opportunistic double agent Yustov (John Van Dreelen) formulates a self-serving scheme that will spell disaster not only for Holman, but for all his loved ones behind the Iron Curtain. ~ Hal Erickson, Rovi
