Salt in the Walls

Slow-burn folk-horror teaser trailer, photorealistic, shot on vintage spherical lenses. Opening: extreme wide of a lone keeper's cottage on a black cliff above a churning slate sea, storm light failing, gulls wheeling in eerie silence; a low tidal drone with a distant bell buoy tolling. Cut to: interior — a widow's crowbar pulls a rotten plank from the parlor wall and a hidden seam of white salt pours out like sand from an hourglass, cascading across the floorboards; the drone cuts to absolute silence except the hiss of falling salt. Cut to: night, candlelight — the spilled salt is arranging itself into a long trembling line pointing at the cellar door, grain by grain; her breath quickens under the bone-dry creak of hinges below. Final shot: the camera plunges down the cellar stairs into darkness as every candle in the house snuffs out at once and something vast and wet inhales; a shrieking string cluster, one thunderous heartbeat, hard cut to black. Desaturated bone-gray grade with crushed blacks and a single amber candle accent, 35mm film grain, volumetric light, ultra-detailed, slow dread-heavy camera movement, trailer pacing, no text, no captions, no watermark.
