When the Soviets invade Czechoslovakia, magazine owner Glenn Howard is on a tour train, watching history take place around him. Peter plays an activist who enlists him to smuggle a subversive manuscript disguised as the novel Tom Sawyer by Mark Twain out of the occupied country. The star-studded cast includs such notable actors as Richard Jaeckel, Susan Saint James, and Roddy McDowall, along with Boris Karloff in his final acting role.

Peter referred to this time in his career as the golden age because he played a variety of characters in well written shows.
