Ray Breslin is a former prosecutor who co-owns Breslin-Clark, a Los Angeles–based security firm specializing in testing the reliability of maximum security prisons. He spends his life getting into prisons to study their designs and the guards' habits to find and exploit their weaknesses, thus enabling him to escape without a hitch. He claims his goal is to ensure that criminals sent to prison stay there due to an unexplained event related to his seemingly dead wife and child.
