A woman with dark, patterned fingernails presses her finger against her open mouth, revealing her teeth, then pulls her finger away as her tongue flicks out. The scene cuts to a woman with long, light-colored hair in a black and white star-patterned outfit, dancing and smiling in a bright, white room. She is joined by other dancers in matching outfits, moving rhythmically. The sequence alternates with shots of a silhouette of a person inside a large, circular, illuminated tunnel, first lying on their back, then sitting up and raising their arms.
