Le prompt

[GOAL]
Handheld walk-and-talk, 15 seconds, one continuous take: on a windy harbour pier, Maud and her mother Odile walk side by side toward the camera and argue in French; the argument escalates until Odile stops dead and says the line that hurts.
[REFERENCE BINDING]
Maud corresponds to @Image 1. Use its close-up for her exact face, including the small scar through her left eyebrow, and its front and back views for her outfit: long dark green waxed oilskin coat over a cream fisherman sweater, navy trousers, black rubber boots.
Odile corresponds to @Image 2 and @Image 3: use @Image 2's close-up for her exact face and @Image 3 for her full outfit. She is in her mid-sixties, grey hair pulled back, deep wrinkles, a vertical scar on her forehead, long dark green coat over a cream ribbed turtleneck, navy trousers, dark green rubber boots, a large brass key on a cord at her waist.
Maud and Odile are two different women: never swap or blend their faces, ages or outfits. Do not reproduce the reference sheet layouts or their gray backgrounds.
The location corresponds to @Image 4: the concrete harbour pier, rusted bollards, iron railing and the white-and-red lighthouse behind them. Use it only for the location.
[CONTINUITY]
Exactly two people on screen. Maud stays on the left of the frame and Odile on the right for the whole shot. The lighthouse stays behind them.
[STAGE 1 | 0-5s | The accusation]
Initial state: both walk briskly toward the camera along the wet pier, wind in their hair and coats. Primary event: Odile, staring straight ahead, not looking at her daughter, speaks first; Maud answers, stumbling over her words; Odile cuts her off before she finishes.
End state: still walking, Maud stung, Odile's jaw clenched.
[STAGE 2 | 5-11s | Maud explodes]
Primary event: Maud steps half a pace ahead and turns toward her mother while still walking, one arm thrown back toward the lighthouse, her voice rising and breaking, eyes wet. Odile shakes her head once without slowing down.
End state: Maud slightly ahead, facing her mother, breathing hard.
[STAGE 3 | 11-15s | The line that hurts]
Primary event: Odile stops dead. Maud takes two more steps, stops and turns back. Odile, quietly, without raising her voice, says her last line, the brass key in her fist. Maud opens her mouth and finds nothing to answer.
End state: the two women facing each other a few metres apart on the pier, wind, Maud speechless.
[VISUAL STYLE]
Grounded documentary realism, flat overcast late-afternoon light, cool desaturated palette of concrete grey, sea green and faded red, natural skin with real texture, 35mm film look, visible fine grain.
[CAMERA AND PERFORMANCE]
Handheld: the camera operator walks backward ahead of the two women, keeping both in a medium two-shot. Continuous small irregular hand tremor and uneven footstep bob. When Maud steps ahead in stage 2, the camera pans to her a little late, overshoots slightly and corrects. When Odile stops in stage 3, the operator stops too with a small jolt, then slowly drifts closer. The shot never becomes smooth or stabilized. No cuts.
Odile: tight jaw, short breaths through the nose, never looks at Maud until her last line. Maud: restless hands, breath catching between words, glassy eyes, a short incredulous laugh before she explodes.
[AUDIO]
<Strong wind buffeting the microphone, waves against the pier, their footsteps on wet concrete.>
No music.
Dialogue language: Belgian French, natural, unpolished, with overlaps.
Odile says: {Tu as signé. Sans m'en parler.}
Maud says, stumbling: {Maman, c'est... c'est automatique maintenant, partout, tout le monde...}
Odile cuts her off: {Tout le monde !}
Maud, voice breaking: {Je suis fatiguée, tu comprends ? Fatiguée de monter là-haut toutes les nuits !}
Odile, quietly, after she stops: {Ton père l'aurait jamais fait.}
Each line is spoken only by its own character, with lips matching the words. No narration.
[No subtitles.]
[EXCLUSIONS]
No on-screen text, no logos, no watermark. No other people. No slow motion, no music, no smooth gimbal or drone movement. No face swap between the two women.
[MAINTAIN CONSISTENCY]
Two women only: Maud matching @Image 1, Odile matching @Image 2 and @Image 3. Maud on the left, Odile on the right. The pier and lighthouse of @Image 4. One continuous handheld take.

Vous obtiendrez

Un plan-séquence de 15 secondes : deux personnages, cinq répliques en français, caméra portée.

À surveiller

Références : @Image 1 = la planche de Maud, @Image 2 et 3 = le visage et le plein pied d'Odile, @Image 4 = la jetée. Chaque personnage garde son côté du cadre du début à la fin. Écoutez la prise avec le son : c'est là qu'on repère une réplique déformée ou ajoutée.
