A street gang named the Dragons begin causing trouble at Rachel's Place, breaking things and sexually harassing employees; Carl arrives just in time to chase them out. That night, after closing time, the gang breaks in and heavily vandalizes the teen hangout. Everyone's anger grows when a bruised and bloodied Eddie arrives, announcing he was ambushed by the Dragons' gang members. Carl wants to take matters into his own hands, but Urkel reminds him that if he were to do that, he'd only destroy much more than his career. Urkel eventually agrees to go undercover as a prospective gang member and trick them into confessing their recent activities.
