COLD OPEN

EXT. SMALL TOWN – NIGHT

A WOMAN in white lace runs through the woods, chased by unseen laughter. She stumbles, falls—then vanishes into thin air as if swallowed by the air itself.

SMASH CUT TO: TITLE CARD – SUPERNATURAL

ACT ONE

INT. BUNKER – LIBRARY – NIGHT

Sam’s at the laptop, Dean polishing a gun.

SAM
People have been disappearing near this old Victorian outside Lincoln. Witnesses say they’ve seen a woman in white lace.

DEAN
(rolling eyes)
Another Woman in White? They need to retire that greatest hit.

SAM
This one’s different. Victims vanish into thin air. No bodies, no EMF traces.

DEAN
(smirking)
So we’re hunting Casper’s bougie cousin. Fine. Pack up.

---

INT. VICTORIAN MANSION – NIGHT

Classic Winchester sweep: salt, flashlights, guns. Dean cracks jokes about “spooky Airbnb vibes.”

Floor collapses. They FALL—

---

ACT TWO

INT. WONDERLAND – CHESSBOARD FIELD – NIGHT

Sam and Dean land on the massive chessboard. Dean swears. Sam realizes it’s Wonderland.

DEAN
We’re in freakin’ Alice in Wonderland? Great. I left my flamingo croquet mallet at home.

Living CHESS PIECES march in. Fight scene. Brothers hold their own but get overwhelmed—Sam captured, Dean escapes.

---

INT. RED KING’S DUNGEON – SAME TIME

Sam meets the Cheshire Cat. Creepy and cryptic.

CHESHIRE CAT
The King dreams. Wonderland dies. You’re in his nightmare now.

Sam tries to press for answers. Cat just grins and vanishes.

---

INT. CATERPILLAR’S GARDEN – NIGHT

Dean stumbles into a surreal forest with giant mushrooms. The CATERPILLAR sits atop one, smoking a massive hookah that smells… suspicious.

CATERPILLAR
Whooooo… are you?

DEAN
(grimacing)
Great. Discount Snoop Dogg. Listen, Smokey, where’s the way out?

CATERPILLAR
No way out. Only in. You’re in the dream. And the dreamer hungers.

DEAN
Yeah, well, dreamer’s about to get a boot up his ass if he doesn’t knock it off.

The Caterpillar blows smoke in Dean’s face—it turns into a vision of Sam locked up. Dean storms off, muttering about “hallucinating bugs.”

---

INT. RED KING’S DUNGEON – SAME TIME

Sam wakes to find the WHITE RABBIT in the next cell—frazzled, muttering, checking his broken watch.

WHITE RABBIT
Late, late, late. Always too late.

SAM
(to himself)
Great. Wonderland’s version of Dean.

Rabbit offers a riddle in exchange for help escaping. Sam solves it with his lore knowledge (“What always runs but never walks?” — “A river.”). Rabbit laughs manically and disappears, leaving the cell unlocked.

---

ACT THREE

INT. MAD HATTER’S TEA PARTY – NIGHT

Dean bursts into the Hatter’s table. Creepy synchronized guests chant “Drink.” Dean refuses, smashes teapot, quips his way through chaos.

DEAN
Tea’s not my thing. I’m more of a whiskey and pie guy.

Fight scene. Dean escapes barely, dragging a sugar-buzzed Wonderland mouse off his boot.

---

INT. RED KING’S PALACE – HALL OF MIRRORS – NIGHT

Sam and Dean reunite, exchanging sass.

DEAN
I just survived a homicidal rave with Mr. Hat-and-Crazy. Where the hell were you?

SAM
Locked up with a cryptic cat and a neurotic rabbit.

DEAN
So… Tuesday.

They march into the throne room.

---

ACT FOUR

INT. RED KING’S THRONE ROOM – NIGHT

The Red King reveals himself. Shadowy, monstrous, shifting. He declares Wonderland his feeding ground and Earth his next.

Dean snarks. Sam explains he’s a Nightmare—lives in dreamscapes, feeds on madness. Weapons won’t work.

Cheshire Cat appears, grinning.

CHESHIRE CAT
Dreams obey their own rules. Break his rules, and he breaks.

Dean smirks, steps forward.

DEAN
(checks his imaginary chessboard)
Checkmate, Your Highness.

The very word collapses the dream logic. The palace crumbles. The King screams, dissolving into flying cards.

---

TAG

INT. VICTORIAN MANSION – NIGHT

Sam and Dean wake on the dusty floor. The portal is gone.

Dean groans, limping toward the Impala.

DEAN
If I see one more teapot, I’m shooting it.

SAM
(smiling)
You do realize you just trash-talked a dream monster out of existence?

DEAN
Damn right. Wonderland can suck it.

They drive off.

DEAN
Next case—beer. Strippers. Strippers with beer.

Sam sighs, but smiles. The Impala roars into the night.

FADE OUT.
