IMPOUND
A contained thriller. One location, one night.

Logline: A night-shift attendant at a city impound lot discovers a kidnapped auditor locked in the trunk of a car she has just signed in — and the only people she can call for help are the ones who put him there.

MARA VOSS (34) — the lot's night attendant. Methodical, sleepless, allergic to asking for help. She works the booth alone to pay down the debt her late brother left behind, and she knows every camera angle, every row, and the location of every key on the property — which makes her dangerous in exactly one place on earth.

DANIEL OKAFOR (48) — a soft-spoken city auditor who followed six figures of missing public money to the precinct's towing contract. Terrified, injured, and smarter than the men who took him.

SERGEANT KESSLER (55) — the cop who runs the impound contract, and the man Mara's brother owed. Patient, friendly, and willing to burn the whole lot down before sunrise.

Night. Rain. MARA VOSS (34) works the booth of a floodlit city impound lot alone, signing in a fresh tow: a gray sedan flagged POLICE HOLD. The tow driver will not meet her eyes and leaves fast. On her hourly walk of the rows, Mara hears it — a slow, deliberate thump from the sedan's trunk. Inside, zip-tied and bleeding, is DANIEL OKAFOR (48). He begs her not to call it in: the officers who took him are the officers on the hold slip. Mara checks the paperwork. The authorizing signature belongs to Sergeant Kessler — the man she mails an envelope of cash to on the first of every month, paying down her dead brother's debt. Procedure says call the precinct. Mara cuts the zip ties instead, hides Daniel in a wrecked RV in row F, and relocks the empty trunk. As she does, the camera feed in her booth flickers and dies — the line has been cut from outside the fence. Headlights stop at the gate. SERGEANT KESSLER (55) smiles up at a camera he knows is dead, and holds up his badge.

Kessler plays it warm through the intercom: a paperwork issue, he just needs ten minutes with the sedan. Mara buzzes him in alone and starts a quiet war on home turf. While he walks the rows, she palms the sedan's key from her cabinet and gets Daniel's story: his evidence — a phone holding a copy of the precinct's books — is taped inside the sedan's door panel. Kessler finds the cut zip ties in the trunk. The warmth goes away. He calls in OFFICER REYES (29), nervous and in over his head, and the two men sweep the lot with flashlights while Mara moves Daniel from wreck to wreck. She holds every key, every alarm, every door — and uses them to recover the phone. It is locked. Minutes later, Daniel is caught climbing the fence. Kessler offers a clean trade: the phone for Daniel's life, and her brother's debt dies with it. Mara almost takes it. Then she finds the tow driver's body in the cab of his own truck — Kessler is not leaving witnesses, whatever she hands over. Reyes torches the booth, intake log and landline inside, and the main gate locks on Kessler's override. Sunrise is three hours away, and no one is coming.

Mara stops hiding. With the master ring on her belt she triggers every alarm in the lot at once — two hundred cars screaming at 4 a.m. — and windows light up across the street, phones already filming the fence line. Kessler's operation needs quiet; the noise splits the two men, Reyes to the gate, Kessler hunting Mara alone. She baits him into the crane bay, the locked phone sitting in plain sight on the seat of a wrecked sedan, then drops the wreck from the magnet crane onto the hood of his cruiser, pinning the door shut with Kessler inside — in full view of a dozen recording phones. Offered one chance to be the officer who called it in, Reyes takes it. Dawn. State investigators photograph the gray sedan where it sits. Daniel, wrapped in a blanket, hands Mara back her unopened envelope of cash. Last image: Mara at a fresh intake form, signing in vehicle 2201 — Kessler's cruiser. Under HOLD she writes: EVIDENCE.
