It’s Frankenstein, but campier. There’s a mad scientist, a lightning storm, a stitched-together monster, and a brain in a jar that just won’t shut up.
Short Synopsis
The Doctor and Sarah land on Karn, where Solon, a delightfully unhinged scientist, is building a body for the disembodied brain of Morbius — an ex–Time Lord despot with all the charm of a hangry Dalek. Naturally, the Doctor and Sarah are soon up to their necks in brain transplants, cultish Sisterhoods, and lots of shouting.
Extended Storyline
Our tale begins when the Doctor and Sarah are forced to land on the storm-swept world of Karn, a planet so atmospheric you can practically smell the mildew. There, they stumble into the creepy castle of Professor Solon — a man who looks like he wandered off the set of Rocky Horror and never went home. Solon is brilliant, eccentric, and about as subtle as a sledgehammer. His “houseguest manners” involve drugging Sarah Jane, throwing shade at the Doctor’s hair, and constantly hinting that he really, really wants a new head for his “special project.”
Said “special project” is a monster stitched together from spare alien body parts — a bargain-bin Frankenstein’s monster. The only thing missing is a head. And guess who just wandered into Solon’s castle with a perfectly serviceable one? Yep. The Doctor. Tom Baker spends most of the story glaring at Solon like he’s about to eat him, while Solon drools over the Doctor’s skull size like he’s at an estate auction.
But Solon’s not just any mad scientist. He’s working on behalf of Morbius, a renegade Time Lord whose brain survived execution and is now sitting in a fish tank, barking orders like a particularly bitter Alexa. Morbius used to be the kind of dictator who made even the Daleks go, “Mate, calm down.” The Time Lords eventually put a stop to him, but, in true Doctor Who fashion, didn’t quite finish the job.
Meanwhile, the Sisterhood of Karn — a cloistered coven of women who’ve been swigging from the Sacred Flame for centuries — are convinced the Doctor has come to steal their elixir of immortality. Instead of asking politely, they immediately attempt to burn him at the stake. Because why have a friendly chat when you can have a bonfire?
Sarah, poor Sarah, spends half the story blinded (thanks, Solon), stumbling around with more courage than sense. She still manages to sass everyone around her, proving once again why she’s the MVP of this era.
Eventually, Solon succeeds in plonking Morbius’s brain into his lumbering patchwork monster. The result: a creature with the body of a galactic yard sale and the voice of a man who desperately needs a lozenge. The Doctor, because he’s Tom Baker and therefore never intimidated, mocks Morbius relentlessly — even while fighting him in a Time Lord mental wrestling match.
This psychic duel is infamous because it flashes images of “previous incarnations” of the Doctor, including a bunch of faces the audience had never seen before. Fans immediately began arguing: Were these earlier Doctors? Were they Morbius’s past lives? Were they just the BBC’s staff photographers in wigs? (Spoiler: it was the last one.)
In the end, Morbius’s monster form is defeated, Solon gets blown up in his lab (classic mad scientist exit), and the Sisterhood decides maybe the Doctor isn’t so bad after all. He gets a bit of the Sacred Flame elixir as thanks — a nice pick-me-up after all that attempted head theft.
