Calla Daniels. That name can instill fear in many different people. An officer to the San Diego Police Department, this girl can kick some serious ass. Spencer Reid. That name does the total opposite. If you met him on the street, you'd think he's a teacher. Only then would he tell you he's part of the FBI's Behavioral Analysis Unit. Two total opposites. One case that brings them closer than they ever thought possible. You know what some people say, Tragedy Brings People Together.
