MIRA We run across the top. Two minutes to the east stairwell—less exposed.

ELI (V.O.) (one beat) Drone on the lower shaft. Divert left at the next junction.

SCENE 4 — HVAC TUNNEL — NIGHT Claustrophobic metal tunnel, humming ventilation. Mira crawls, teeth chattering. Through a grate, she sees Kara’s silhouette walking confidently beneath—too close. Mira holds her breath, heartbeat loud.

SCENE 6 — ROOFTOP SPINE — NIGHT They sprint across a narrow ridge between buildings. The helicopter light sweeps. A net launcher fires from a neighboring roof and misses, snagging an antenna. The wind howls; Mira slips. Eli grabs her hand—grip tight. They leap a gap between roofs. For a moment, time slows; city lights smear.

She moves toward the access door. Footsteps thunder in the hall below. She freezes.

SCENE 3 — STAIRWELL — NIGHT Narrow, fluorescent flicker. Mira descends quickly. Her phone buzzes; she ignores it. On the landing, a security drone's shadow glides past, searching. Mira times its sweep, squeezes past a maintenance door, and ducks into a service corridor.
