Invitation to the Undertide

Rain hammers corrugated metal. Police FLOODLIGHTS slice through sheets of storm.

MARA KELLS, soaked paramedic jacket over scrubs, kneels beside a YOUNG MAN on the pavement—alive, shaking, face bruised. His fingers clutch at his own throat like he’s trying to pull out a thought.

SHERIFF BECK RUSK stands over them, broad silhouette under a dripping hat. His deputies keep their distance, like the air here bites.

She— she smiled at me. I remembered… proposing. I don’t even know her name.

Easy. Breathe with me.

She presses gauze to his split lip. The gauze blooms pink, then— for a blink—darkens to an impossible crimson and dries too fast.

BECK notices. His eyes flick to Mara’s hands.

That’s the third lover in two weeks. Same story, different face.

People get hurt in storms.

Not like this. Not with poems carved into knuckles.

He nods to the YOUNG MAN’s hand: crude letters dug into skin—ALWAYS YOURS.

BECK (CONT’D)

You’ve been first on scene every time.

MARA’s jaw tightens. Thunder rattles the alley.

BECK (CONT’D)

And every time, it’s within a block of this place.

He looks up. The building is anonymous brick—no sign, no windows. Only a SERVICE DOOR with an old brass pull that seems too polished for the weather.

It’s a storage building.

Storage doesn’t make folks lose their minds for love.

A beat. Rain. The YOUNG MAN whimpers, staring past Mara—at the door—like it’s someone’s eyes.

Tell her I— I remembered the ring. I remembered the ring—

MARA grips his wrist, grounding him.

You’re safe. You’re here.

BECK watches Mara do her job—then steps closer, lowering his voice.

Kells. Off the record.

MARA looks up. His face is hard, but not cruel.

BECK (CONT’D)

If there’s something in there that’s doing this… you tell me now, and I’ll keep it from chewing through this city.

You don’t know what you’re asking.

I’m asking for the truth.

MARA’s eyes dart to the door. For half a second, the brass pull looks like a LOCKET—heart-shaped—pulsing under the floodlight.

MARA flinches.

BECK sees that flinch like a confession.

BECK (CONT’D)

You’ve been inside.

MARA stands, blocking Beck’s line to the door. She forces her voice steady.

Go home, Sheriff. Let the storm pass.

Storm’s not the problem.

He reaches into his coat and pulls out an evidence bag. Inside: a tiny charm, slick with dried blood. It hums faintly, like a distant choir.

BECK (CONT’D)

Found this on one of them. Warm when I picked it up.

MARA’s face drains. She recognizes the feel of it—blood-warm, whispering.

Don’t—

Too late. BECK’s thumb presses the plastic, touching the charm through it.

The FLOODLIGHTS FLICKER.

For an instant, BECK’S expression softens—eyes glassy, mouth parting as if hearing a lover say his name.

BECK (whisper)

June…

MARA snaps the bag out of his hand and shoves it into her medical kit, breath ragged.

You can’t touch it.

BECK blinks hard, anger returning like a slammed door.

What the hell is “June”?

Nothing.

BECK steps in. Close now. Rain between them like static.

I don’t have a June.

MARA’s silence is answer enough.

A LOW, VELVET VOICE slips from the darkness behind the service door—calm, intimate, dangerous.

LUCIEN (O.S.)

Sheriff Rusk. You’re standing in a threshold you don’t understand.

The door is still shut, but the voice is right there—as if the building breathes through the seams.

BECK draws his gun, instinctive.

Show yourself.

MARA’s eyes flick to the door, pleading without words.

Luc—

LUCIEN (O.S.)

Mara.

Her name in his mouth is a touch. It steadies her—and ignites something possessive behind her ribs.

BECK aims at the door.

Mara, step away from it.

MARA doesn’t. She shifts—subtle, protective—between Beck and the unseen man.

If you go in there with that badge and that gun… you won’t come out with your own memories.

Then I’ll bring a warrant.

LUCIEN (O.S.)

Paper doesn’t survive the Undertide.

The storm surges. Water races along the curb like it’s being pulled somewhere.

BECK lowers the gun a fraction, fighting the pull of whatever he just felt—June’s ghost on his tongue.

You’re telling me a building is rewriting people’s love.

MARA swallows. The truth tastes like betrayal.

I’m telling you it’s hungry.

A beat. Beck studies her—sees fear, sees devotion, can’t tell which is worse.

You have until sunrise.

He gestures to his deputies.

BECK (CONT’D)

Clear out. Take him to County.

The deputies lift the YOUNG MAN onto a stretcher. As they wheel him away, he reaches toward the door, crying out.

Always yours!

MARA watches him go—then turns to the door, drenched and trembling.

He touched it. He felt something.

LUCIEN (O.S.)

So did you.

The brass pull clicks—just once—like a heartbeat inviting her in.

You said the relic was contained.

LUCIEN (O.S.)

It’s learning.

MARA’s hand hovers over her kit—over the evidence bag—over the warm hum inside.

She makes her choice.

Open the door.

The SERVICE DOOR unlatches itself.

And the darkness within exhales, waiting.
