Teenager Jacob Hunt has Asperger's syndrome. A forensic science wizard, he shows up at crime scenes and gives law enforcement officials his advice. But when his tutor is found dead, he becomes a suspect. Suddenly, his Asperger's traits - not looking people in the eye, tics and twitches - look more like guilt in the view of police. And Jacob's mother must ask herself the hardest question in the world: is her child capable of murder?
