The Doctor faces off against a space pirate with a planet-sized ego — literally — while Douglas Adams sneaks in enough jokes to power a Vogon poetry recital.
Short Synopsis
The Doctor, Romana, and K-9 head to the planet Zanak, a world that vanishes and reappears across the galaxy like a badly-programmed screensaver. Its secret? Zanak isn’t just a planet — it’s a hollowed-out mining ship that materializes around other worlds, crushes them, and hoovers up their resources. At the helm is the blustering, cyborg Captain, whose plans are even bigger (and greedier) than his prosthetic limbs. Naturally, the Doctor and Romana aren’t about to let a galactic real-estate scam of this magnitude go unchallenged.
Extended Storyline
Fresh off their first successful scavenger hunt (and Romana’s smug reminder that she’s still top of the class), the Doctor and Romana arrive on Zanak. At first, it seems pleasant enough: citizens live in comfort, gold is handed out like candy at Halloween, and everyone seems curiously unbothered by their planet’s constant disappearances. The locals chalk it up to “the Captain” — their ruler, a half-man, half-machine with a booming voice and the temperament of an over-caffeinated drill sergeant.
It quickly becomes clear that Zanak is essentially the galactic equivalent of a parasite Airbnb. The planet’s crust is hollow, its machinery allowing it to materialize around other worlds. Once it locks into position, it crushes the victim planet, drains its minerals, and keeps the spoils for itself. Entire civilizations reduced to rubble in seconds — but hey, free gold coins for the locals!
The Doctor is horrified, Romana is appalled, and K-9 is positively itching to shoot something. They discover that the Captain himself is not entirely in control. He’s more of a blustering figurehead, stomping about the bridge, screaming “MOI MINES!” and punctuating every line with manic laughter. His real master is Queen Xanxia, a tyrant who should be long dead but has preserved herself in suspended animation. Her surviving consciousness is running the show, using the Captain as a pawn while she plots to restore her own youth and rule forever.
Naturally, this doesn’t sit well with the Doctor, who much prefers his villains to be alive, arrogant, and defeatable. Romana, meanwhile, proves her mettle by analyzing the Key to Time’s signal and keeping pace with the Doctor’s deductions. Their teamwork begins to settle into a rhythm: his improvisational chaos bouncing off her clinical precision.
The stakes escalate when the Captain targets Calufrax, the Doctor’s intended destination — which, surprise surprise, happens to be the disguised second segment of the Key to Time. If Zanak consumes Calufrax, the segment will be lost forever. Cue running, scheming, and a fair amount of shouting.
The climax is a glorious mess of Adams-style absurdity: the Doctor outwits the Captain, K-9 blasts robot parrots out of the sky (yes, really), and Romana saves the day by helping identify the segment just in time. The Captain, in a bizarre twist of villainous dignity, attempts to defy Queen Xanxia and take her down with him, but the plan backfires in suitably explosive fashion.
The story closes with the Doctor and Romana recovering the second segment, K-9 smugly polishing his laser, and the universe breathing a sigh of relief that one more megalomaniac won’t be hollowing out its planets. Romana, however, remains unimpressed by the Doctor’s tendency to “wing it.” He just grins, offers her a jelly baby, and promptly steers the TARDIS toward the next disaster.
