Vicki and Aaron Newton are separated, with joint custody of their two sons, Aaron (12) and Kobe (5). Though the boys are angels for Dad, young Kobe saves his worst behavior for Mom. He is violent and destructive -- hitting, kicking, slapping, punching and swearing. He even throws rocks at Jo's head. Aaron isn't physically aggressive, but he does talk back to his mother. For the first time, Jo Frost observes life in two homes to hone her recommendations for each parent. But can she get them to collaborate on their child-rearing techniques?
