Use this high-altitude swing-chase sequence to build a fifteen-second 16:9 action film in one continuous drone shot. An adult heroine falls backward from a skyscraper edge, fires a thin tether, swings between towers, runs across a wall, redirects into a second swing, lands on a rooftop, and defeats one black-suited villain before shouting and leaping onward. The timing emphasizes gravity, line tension, foot placement, body weight, readable momentum, and stable identity. Strict rules prevent cuts, teleportation, hovering, clones, extra enemies, branded superhero symbols, broken anatomy, camera collisions with buildings, subtitles, and watermarks.
