Intro: The Daleks are merciless, unfeeling, and rapacious. The Exxilons are savage, degenerate, and hostile. Not exactly the kind of folks you'd like to invite to a party, unless of course you're a profoundly masochistic bent. The trouble is, The Daleks and The Exxilons don't always wait for an invitation.

Outro: Meanwhile, on Peladon, the spirit of the sacred monster Aggedor is spreading terror and death. Let us fervently wish that the situation does not degenerate to the point it cannot be righted by The Doctor next Sunday night when he confronts "The Monster of Peladon." [source: ChicagoEpguides]
