Intro: The Doctor begins an odyssey to Skaro in an attempt to save future generations from the menace of that conscienciousless race whose single-minded purpose is unmatched in the universe, except by the Orkin man.

Outro: With the wicked, whopper wasps dispatched, nothing blocks the Earthlings' return to begin repopulating their planet, or so they believe. They will learn differently next Sunday night at 11 when we embark on 'The Sontaran Experiment.' [last week's outro was played in error] [source: ChicagoEpguides]
