Max, a forty-four-year-old, severely obese man who lives in New York, is pen pals with Mary, a lonely eight-year-old girl who lives in the suburbs of Melbourne. He shares more about himself by describing a condition he has: Asperger's Syndrome.
A couple brings their autistic son to Harbor Neuroscience in New Hampshire to seek the advice of a specialized doctor. He provides them with general information about the disorder and encourages the parents to not see their child as less than other children but as different. The doctor strongly urges them not to set low expectations for their son, because perhaps he can exceed them to a degree highly unpredicted.
