黑衣女子在地下麻将馆迎战群匪

A gritty, cinematic, photorealistic 20-second urban martial-arts action scene in 16:9, in the style of a 1990s Hong Kong / Korean crime-thriller. Handheld camera with sharp whip pans, rapid cuts, shaky close-ups, motion blur and flying debris. Color grade: cold blue-grey haze, desaturated teal and brown tones, deep shadows, a faint film grain, thick cigarette smoke drifting through the air, flat fluorescent tube lighting and a few warm amber lamps.

SETTING: A run-down underground mahjong parlor in an old building: stained concrete floor littered with broken glass and mahjong tiles, scuffed wood-paneled walls with framed pictures, green-felt mahjong tables with white tiles, green glass soju bottles, wooden chairs, a brown leather sofa, an old CRT television on a wooden stand glowing white static, ceiling fluorescent tubes, smoke and dust in the air.

HERO: A young woman with brown shoulder-length wavy hair in a loose, messy ponytail with bangs, wearing a black turtleneck, a worn black leather jacket and black trousers. Fierce, calm, cold expression. She fights with precise, powerful strikes, kicks and throws, using chairs and bottles.

THUGS: A gang of men in black leather jackets and dark clothes. The first is a heavyset, bearded man with short black hair, a big grin and a metal dog-tag chain around his neck.

Shot 1 (0–2s): Medium close-up. The big bearded thug grins and reaches out his hand toward her face to touch her chin. She stands with her back partly to the camera, head turned toward him. His face goes from a leer to alarm as she hits back.
Shot 2 (2–3s): The thug is flung backward with his arms flailing above his head, falling toward a mahjong table in the background.
Shot 3 (3–4s): He crashes into the green felt mahjong table, a bottle and white mahjong tiles exploding into the air around him.
Shot 4 (4–5s): Close-up: the woman turns to the camera, face cold and focused, hair strands in front of her face. Behind her another thug grins and swings a wooden chair at her.
Shot 5 (5–6.5s): She ducks under the chair, which smashes against a wall in a burst of splinters. Fast whip pan to a thug thrown against the wall, then a low shot of his legs kicking and another man sliding across the floor.
Shot 6 (6.5–8s): Wide shot: an old CRT TV in the background, a thug runs in and she sweeps him down; he slams across the edge of a mahjong table with tiles scattering. A thug crawls on the floor.
Shot 7 (8–9s): A grinning thug lunges at her with a green bottle. She dodges, grabs his arm and smashes the bottle, glass spraying; close-up of her fist and the bottle breaking in a spray of liquid.
Shot 8 (9–11s): Rapid close-quarters fight: she punches a thug in the face, spins, and he is knocked backward; a thug lounges on a brown leather sofa, stunned, as another body passes the lens; she turns and kicks.
Shot 9 (11–15s): Chaotic brawl in the smoke: multiple thugs rushing in, handheld shaky camera, her ponytail whipping, punches and elbows landing, a man yelling in rage, then a low-angle shot of black trouser legs mid-kick. One thug grabs her by the shoulders; she throws him over her hip.
Shot 10 (15–16s): Low shot across the floor: a defeated thug lies on the glass-strewn floor, tiles and green bottles around him, her black trouser legs step past the camera.
Shot 11 (16–18s): Wide static shot: the woman stands in the center of the wrecked parlor, legs apart, chest heaving, rubbing her arm, her head lowered, bodies of the thugs sprawled on the floor and chairs, broken chairs, bottles, the old TV flickering white.
Shot 12 (18–20.5s): She slowly raises her head and walks toward the camera; the camera pushes in slowly from a medium shot to a tight close-up of her face, wet hair strands across her forehead, breathing hard, staring straight into the lens with a cold, defiant look.

Audio: heavy thuds, bone-crunching punches, glass shattering, wood splintering, mahjong tiles scattering, men yelling and groaning, a low tense drone with a pounding drum beat that cuts to near silence on the final close-up with only her heavy breathing and the hiss of the TV static.
