A teenage boy is found wandering, naked and dazed, in traffic. At a nearby youth detention center, authorities discover that this kid -- Kyle -- is a savant who's missing instinctive human behavior like joy, anger and love. Stranger still, he's missing the one thing every mammal has: a belly button. One of the center's psychologists, Natalie Trager, realizes that Kyle needs special attention -- so she brings him home to live with her family. Soon, Kyle starts to investigate his origins ... and some people aren't too happy about it. Wikipedia
