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. Nicky is 19. After making good progress at DLC Warren he is about to leave, but the prospect of change leads to increasing anxiety and erratic behaviour. Surrounded by a loving family who say they wouldn't have him any other way, he shows Louis his novel Dragonula and invites him to share his first day at his new school. Twenty-year-old Brian is severely autistic and his behaviour - setting fire to the house and attacking his mother - has led to the difficult decision of placing him in residential care. Louis meets a mother whose love for her son has been tested to its limits and finds out how the school is preparing him for an adult life.
