David doesn't recognize anybody at his new high school and he never will, due to a neurological disorder that prevents him from recognizing people's faces. With the help of a best friend, David manages to keep his disorder a secret and lead a normal life.
But then David witnesses that friend's murder, and even though David can't identify the killer, the killer has no problems identifying David.
