Two figures swim through a vast, red-tinged underwater environment, their movements slow and deliberate against the dark, shadowy seabed. The scene cuts to a close-up of a young man with spiky hair, his face illuminated by a red glow as he looks upward, followed by a sudden shift to a close-up of a man with a red, glowing eye and a terrified expression, then to a woman with wide eyes, before ending on a wide shot of a lone figure standing on a brightly lit, striped pedestrian crossing at night, surrounded by blurred figures of people walking.
