A little dictator named Dylan rules the roost in the Van Ackers' Oak View, California, home, and parents Jessica, 34, and Kevin, 35, need to be liberated from his relentless tantrums and disrepect. Now three years old, Dylan refuses to be potty-trained and, worse, he's become anemic from his unbending preference for sugary snacks over vegetables and other nutritious foods. Supernanny Jo Frost embarks on a family revolution to instill parental discipline for the benefit of all, including six-year-old Emma, who can't even have quiet homework time with Mom without the distractions of her little brother's constant crying and complaining. It's a primetime clash of wills with more at stake than calm and discipline, as Jo tries to create a new household order necessary for Dylan's health.
