By Sir Arthur Conan Doyle. Adapted by John de Lancie from a script by Nat Segaloff and John de Lancie.
Cast: 4m., 2w. (11 m. or w., extras.) Remember the good old days of radio—when people had to use their imaginations—when the mind was a stage? Those days are back—only better! You can SEE as well as HEAR radio programs. Challenged by his colleagues to prove his extraordinary claim that prehistoric animals exist and that he has seen them, Professor Challenger leads a harrowing four-man expedition through the remote jungles of South America to settle once and for all the validity of his claim.
