A continuous, high-tension cinematic sequence inside a steamy retro green-tiled bathhouse. The camera establishes a man relaxing in a pool, face covered by a hot towel. Black-gloved hands enter the frame from the steam behind him. The action escalates rapidly as the man is violently pushed underwater. The sequence shows chaotic angles of intense struggle, massive bubbles erupting from below the surface, and a wet hand desperately gripping the pool edge before slipping. The scene resolves into a slow, quiet shot of the single white towel floating on the now-calm water surface. Moody lighting, film grain. 16：9 4K
