The one where the Doctor, Mel, and intergalactic rogue Sabalom Glitz stumble onto an icy planet run by a vampire-like overlord, meet a teenage rebel named Ace, and discover that sometimes cliffhangers involve literal cliffs.
Short Synopsis
On Iceworld, the Doctor, Mel, and Glitz hunt for a mythical treasure guarded by a dragon. They find not just riches but new companion Ace, a street-smart teenager armed with Nitro-9. Cue betrayal, explosions, and the departure of Mel in the least tearful goodbye ever.
Extended Storyline
We begin on Iceworld, a frosty shopping mall/fortress run by Kane, a cold-blooded overlord with a freezer obsession and the bedside manner of a particularly grouchy Dracula. Kane sells weapons, rules with an icy fist, and keeps his minions literally frozen until needed. His long-term goal? Break free from Iceworld and return to his home planet to conquer it. Subtle, he is not.
The Doctor and Mel pop in with Glitz, who’s hanging around being his usual charming, dodgy self. Glitz is after treasure — because of course he is — and drags the Doctor along to hunt for the legendary “Dragonfire,” a mysterious power source supposedly hidden in the depths of Iceworld. Naturally, there’s a map, a labyrinth, and a guardian dragon. It’s basically Indiana Jones by way of a BBC storeroom.
Enter Ace. She’s a 16-year-old from Perivale, a London suburb, who was accidentally zapped across time and space by a freak time storm while experimenting with explosives in her bedroom. (As you do.) Ace is everything Mel isn’t: sarcastic, rebellious, and armed with cans of homemade Nitro-9, which she cheerfully deploys whenever something looks even slightly explode-worthy. She quickly clicks with the Doctor, forming a bantering, more equal partnership that sets the tone for the rest of the McCoy era.
The treasure hunt leads the group deep into Iceworld, where the sets become icier, the corridors narrower, and the budget increasingly obvious. Along the way, we’re treated to the infamous cliffhanger: the Doctor decides to literally climb down a sheer ice cliff with his umbrella. He dangles precariously, looks like he’s about to plummet to his doom… and that’s it. Cue credits. The next episode reveals he could have just stepped off safely onto a ledge about three feet below. It’s widely regarded as one of the most unintentionally hilarious moments in the entire series.
Meanwhile, Kane broods in his icy lair, freezing disobedient henchmen and whispering about conquest. His origin story is pure space opera: exiled from his planet centuries ago, he’s cursed to remain on Iceworld, plotting his inevitable return. He also has the classic “villain can’t survive daylight” weakness, which will be important later.
The dragon turns out not to be a monster but a biomechanical guardian with the Dragonfire crystal inside its head. This crystal is the key to Kane’s freedom, and he’ll stop at nothing to get it. Naturally, the Doctor outsmarts him — but not before Kane gets his icy hands on the crystal and prepares to launch his revenge mission.
Too bad for him, the Doctor reminds Kane he can’t leave Iceworld because of that pesky sunlight allergy. Kane, in classic overdramatic villain fashion, decides to open a window anyway. He’s immediately incinerated by daylight, leaving behind a melted pile of villain goo. Evil thaws quickly on Iceworld.
The story wraps up with Mel deciding, out of nowhere, that she’s leaving the TARDIS to go traveling with Glitz. The farewell is bizarrely upbeat — she practically skips off, saying she’ll “keep an eye on” him, which is like volunteering to babysit a kleptomaniac raccoon. The Doctor barely looks fazed. But Ace, impressed by the Doctor and eager for adventure, happily takes Mel’s place, officially joining the TARDIS crew.
And with that, the Seventh Doctor’s real era begins.
