Jonathan Cord is a serial killer. Or is he? The police and FBI think so and are trying everything in their power to find and stop him. Why is he killing men, women and children? Because he is insane, or is it because there’s something–or someone–else involved? Only Cord knows the demons which drive him to kill. Will the team of FBI profilers learn what those demons are in time to stop more killings? Or will they become victims themselves?
