In Springfield, the men and boys become fixated on the brutal Ultimate Punch Kick and Choke Championships, where competitors unleash extreme violence on each other. In response, Marge and her friends organize a protest against the event, but the promoter seizes the moment and dares Marge to step into the ring, vowing to end the championship if she defeats him. Determined, Marge starts training with rhythmic gymnastics, but her family intervenes and arranges for her to receive professional martial arts coaching, giving her a fighting chance to triumph.
