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.

It soon becomes apparent that the shooting is somehow related to the killing of his family 18 months before.
