In America nearly one child in a hundred is diagnosed with an autism spectrum disorder - a brain disorder characterised by an inability to socialise and communicate. Louis travels to DLC Warren in New Jersey, one of the most innovative autism schools of its kind, to find out how specialised intervention can help both the children and the families who care for them. He meets Joey, whose mother Carol is finding it increasingly hard to cope with some of the more challenging aspects of his disorder. In between the ever more explosive tantrums, Louis discovers a cheeky and charming 13-year-old, but there are tough decisions ahead about his future in the family home.
