Double episode Doctor Who adventure set on the planet Karfel and in nineteenth century Scotland. The Sixth Doctor (Colin Baker) and Peri, accompanied by a young man named Herbert, become entangled with the machinations of the despotic Borad. Planet Karfel consists of a small population ruled by a despotic, Wizard of Oz-like autocrat called The Borad. The Borad has never been seen in the flesh - only by means of closed-circuit television monitors wherein he appears a somber, upright old man. His rule of fear is enforced rigidly by an army of androids who destroy all dissent in a blink via the Timelash - an instant and irreversible exile to another, presumably horrific dimension. One member of the grand counsel immediately below The Borad, (called the Maylin) is less than happy with The Borad and seeks 'regime change' at any cost. A race of former allies called The Bandril sees weakness and opportunity in The Borad's semi-visible ruling methods and is set to invade. It is into this volatile situation that the Tardis materializes and our favourite time travelers are cast.

Talk about your mismatched neighbors In The Duplex, two pairs of absolutely opposite tenants rule their own domain, with only a four-inch wall to separate them. Over-confident bachelor slob Eno and his faithful dog Fang control their ultra-macho haven on one side, while fashion-savvy Gina and her poodle Mitzi do their color-coordinated thing on the other. Clueless Elvin lives next door, livening up the proceedings in a straight-man role. The setup provides plenty of laughs
-- On the duplex's distaff side, Gina and Mitzi sit down to dinner: Thank you God for this delicious food and drink that you've blessed us with.... On the guy's half, the meal begins with, Thank you God for our sprinkler system.
-- Sitting in front of the TV, Gina emits a tiny burp: Boy, I'm glad no one was around to hear that Next door, Eno's belch booms out: Rats No one was around to hear that
-- When Mitzi announces to Gina that her mother's coming over, Gina responds, Maybe we should clean up the place. But at Eno's house, the same declaration from Fang gets a different reply: Maybe she'll clean up the place.In addition, The Duplex serves up hilarious strips that feature each camp as they're involved in their own lives. Eno picking up women at a bar; Gina pulling out her scales to weigh herself at a restaurant; Fang shearing the lawn with his beer-swilling owner atop the mower.
