A shirtless man in black briefs and crutches stands on a platform, then steps onto a transparent rectangular frame, balancing on one crutch while the other is held aloft, as a stream of liquid sprays from his crotch area. He remains on the frame, looking upward, as the stream continues to spray forward, then turns his head to the side. The scene takes place in a minimalist indoor space with a plain wall and floor.
