WTTW split the story into two episodes, with the break occuring during episode four when the Doctor points out to Hart that the submarine signal is heading towards the beach near the prison. [source: ChicagoEpguides]

Intro: As you may recall, The Doctor and Jo were in dire straits when last we observed. That notwithstanding, I am constrained to invoke the phrase popularized by entertainer Al Jolson when he said "you ain't seen nothin' yet." The Master and the Sea Devils will form an unholy alliance, the grim results of which cannot be imagined. Fortunately, we won't have to imagine. We'll be astonished observers of the conclusion of "The Sea Devils." [narration by Don Ferris]Outro: And so The Master has escape to plague us all another day. One must admit that life would be less interesting without him. We will not be seeing him next week. Our heavy will be a mean spirited, sadistic fellow called The Marshall who delights in hunting the mutants of the planet Solos and other abominations, which will remain unrevealed until next Sunday night at 11.
