At the university, in the classroom. A physics experiment. A woman is facing the camera, standing on a metal circle on the floor surrounded by numerous vertical lasers. She is standing upright, arms at her sides, feet together. She has invisible clothes, so she looks completely naked and barefoot. Because of the lasers, the young woman takes on a green hue. All that can be seen of his clothes—top and bottom—are the outlines, traced by green lasers. The right half of his body is wearing real clothes, the left half is just laser lines. The teacher points at the young woman.
