EXT. WAREHOUSE DISTRICT - NIGHT

Rain hammers the cracked asphalt. A figure in a long coat moves through shadows, collar raised against the downpour.

He stops. Checks his watch. 11:58.

MARCO
He said midnight. He meant now.

A door opens across the street. Yellow light spills out.

CUT TO:

INT. WAREHOUSE - CONTINUOUS

Marco enters. The space is empty except for a chair in the middle — and the man sitting in it.

Freehand Draw
Draw directly onto any panel. No drawing tablet required — mouse or touchscreen
AI Generation
Type a shot description → AI generates a reference image. Powered by Pollinations.ai — free, no API key
