Seventeen-year-old Jazz Dent, the son of a notorious serial killer, battles the legacy of his father while using his intimate knowledge of killers to help the local sheriff profile and catch a copycat murderer terrorizing their town. As suspicion, bullying, and his own dark impulses mount, he must prove he isn't destined to follow in his father's footsteps while uncovering clues that blur the line between hunter and hunted.
