Plot
Amos Decker is a former professional football player who was violently hit on his first play, resulting in severe injuries and changes to his brain. As his football career has ended, Decker becomes a police officer, and later a successful detective, while using his newly acquired mental abilities (synesthesia and hyperthymesia). After his family is murdered in an unsolved case, Decker loses his will to live, and becomes a transient while working as a private investigator.

After a mass shooting at a local high school, Decker is asked to assist in solving the case by the local police force he used to work for. It soon becomes apparent that the shooting is somehow related to the killing of his family 18 months before.
