In a medium shot, two boys practice martial arts in a gymnasium on a gray mat. The taller boy, barefoot, wears a khaki shirt and black shorts, holding his arms up in a defensive posture. His right leg is extended horizontally, supported by the other boy. The shorter boy, also in black shorts, wears a black t-shirt and white socks on his right foot. He grips the taller boy's leg with both hands, maintaining his own defensive pose with his left hand raised. Behind them, a woman performs floor exercises. The gymnasium is illuminated by fluorescent lighting and the walls are adorned with colorful flags. Windows line the left side of the frame, offering a view of a cityscape. The camera is stationary throughout.
