Kyle XY is an incredible mystery about a teenager with no past. The series tells the surprising journey of Kyle, a 16 year-old teenage savant who is missing instinctive human behavior such as anger, joy and love, and the family who found him. After coming out of the woods and found walking into traffic, Kyle is sent to a youth detention center where he comes into contact with his first experience of eating food and human interaction: not all of it friendly. At the center they realize that Kyle is not like any ordinary teenager, especially once they find that he is missing his belly-button. With questions of 'Who is this kid?' and 'Where did he come from?' psychologist Nicole Trager is called in to help get some much needed answers.
