A man in a blue jacket holds a red shield as another man in red and black pants performs a kick, causing the man with the shield to fall to his knees; the scene repeats with the man in the blue jacket standing and facing the group, while the man in red and black pants stands with his back to the camera, and the man with the shield falls to his knees again. The setting is an indoor gymnasium with a green floor marked with white lines.
