Gothic cinematic horror teaser trailer, photorealistic, shot on anamorphic lenses. Opening: aerial extreme wide of a drought-emptied reservoir at dusk, cracked mudflats spiraling down to a drowned abbey exposed for the first time in sixty years, its bell tower leaning; a low choral drone that could be wind or voices, deliberately ambiguous. Cut to: a sound archivist wading the flooded nave in headlamp light, boom microphone raised, tape reels turning — through her headphones the silence resolves into faint plainsong in perfect Latin, and she looks up at the empty choir stalls; only recording hiss and the impossible singing. Cut to: extreme close-up of black water rising silently around her boots though no rain falls, the plainsong adding voices one by one, each new voice pitched slightly deeper than a human throat; a sub-bass swell felt more than heard. Final shot: the abbey bell heaves itself upright in the tower and rings once, mud pouring from its mouth, as the flood roars back over the valley toward the camera; a full choral scream synced to the bell, hard cut to black and a single drip in the dark. Waterlogged green-black grade with crushed shadows and pale headlamp bloom, 35mm film grain, volumetric fog light, ultra-detailed, slow dread-heavy camera movement, trailer pacing, no text, no captions, no watermark.
