The female instructor at the slave retraining center leads slave No. 1, who had run away from his Mistress and been sent to the center, out of the cell and punishes him with a flurry of slaps as punishment for running away. The instructor sits on a chair and makes the slave hold a gag ball in his mouth and crawl around the chair to train him to walk on all fours. If the slave walks too slowly, the instructor hits him with a riding crop, spits on him, pinches his nipples, and slaps him. The instructor turns the slave into a ponyboy, gets on his back, and makes him walk on all fours while enjoying the ride. Every time the slave gets tired, the instructor whips him, tramples on him with her heels, slaps him, and makes the slave continue training by walking on his back with the instructor on. The instructor retrains the slave while enjoying his own sadistic tendencies, and sends him back to his Mistress as an excellent slave.
