Preserve the exact face, hairstyle, golden-cream dress, tattoos, necklace, and overall appearance. She lies feverish and restless in the upper bunk of a dark sleeper train, slowly waking as her fingers tremble and dark veins appear. Her eyes turn cloudy white, her expression becomes unnaturally blank, and a dark drop falls onto the passenger below. She suddenly leans over, drops onto the lower bunk, and attacks the sleeping passenger non-graphically. Dark veins spread across him as he convulses, his eyes turn white, and he releases an inhuman scream.

The infected passenger rushes into the corridor, awakening others and triggering chaos throughout the carriage. Curtains fly open, luggage falls, passengers scramble to escape, and more people become infected. A conductor grabs a fire extinguisher and blasts the approaching infected with white foam, giving survivors time to reach the connecting door. They slam it shut and barricade it with luggage and a fold-down seat as infected hands pound against the glass. Cracks begin spreading while terrified passengers retreat.

End with survivors huddled together beneath flashing red emergency lights, protecting two children as the sealed door violently shakes behind them. Cut to an exterior wide shot of the train speeding through the dark countryside, sleeper-car windows flickering with red emergency light and chaotic silhouettes inside. Ultra-realistic cinematic zombie horror, authentic sleeper-train interior, blue night lighting, red emergency lights, realistic characters, handheld camera during chaos, practical effects, atmospheric shadows, tense sound design, no background music, no excessive gore, no subtitles, no watermark, no anime or cartoon style.
