Intro: Flappers, a costume ball, and a killer on the loose! They add up to the first completely historical, non-sci-fi adventure in fifteen years. Monstrous, you say? Monsterless, I say-- but veeeery interesting! As we shall observe, in the unfolding of.. the "Black Orchid", here on WTTW, Channel 11, in Chicago.

Outro: Who or what has ruthlessly slaughtered a group of 25th century paleontologists in an underground cave? Lt. Scott and the security force trooper set out to find the answer, but this is a job for The Doctor. The tale will be told next Sunday night at 11. Be prepared for "Earthshock."
