[Visual Structure] As the floor collapses from behind, the world rotates 90 degrees every time the protagonist steps on a wall, making the wall the new floor. She escapes by switching to walls and the ceiling, returning to the original floor just as the collapsing stops.

[Key Scene (must include in Shots 5-7)] The fallen iron plates assemble themselves below, forming a staircase that follows the path she ran.

Shot 1 (Rotation Hook): Midnight construction site. The moment the protagonist steps on the wall, the world rotates 90 degrees with the camera, turning the wall into the new floor. She stares ahead with a serious gaze.
Shot 2 (Pursuit): The floor collapsing from the edges closes in. The only escape routes are the walls and ceiling. The protagonist calmly and quickly assesses the situation.
Shot 3 (Wall Sprint): The protagonist sprints at full speed along the wall. She jumps over windows and signs as obstacles. Sharp expression of deep concentration.
Shot 4 (To the Ceiling): Another 90-degree shift to the ceiling. Only her hair and clothes remember the gravity from a moment ago, settling with a delay. Her expression remains steady.
Shot 5 (Threading the Gaps): Weaving through the gaps of the collapsing floor. A composition where up and down become indistinguishable. She runs through while calmly regulating her breathing.
Shot 6 (Final Transition): Returning to the original floor in the final transition. The floor collapsing stops abruptly. At the moment of landing, her mouth relaxes slightly.
Shot 7 (Stasis): The protagonist fixes her hair and says with a cool face, "It was a shortcut." On the wall behind her, only footprints are lined up vertically.
