Intro: If the Doctor can escape the Earth's moon, he must still convince the president of the Earth and the Draconian leaders who is really behind the attacks. His work is cut out for him in the conclusion of "Frontier in Space."

Outro: Somewhere, a mighty army of Daleks is waiting. Next week, The Doctor and Jo set off in pursuit. Be with us next Sunday at 11 for part 1 of "Planet of the Daleks." [source: ChicagoEpguides]
