Ken Rex McElroy terrorized Skidmore, Missouri for decades. On July 10,1981, 60 people surrounded his truck and shot him dead. No one claimed to see a thing, with the town keeping quiet, local investigators have a tough case on their hands.

Skidmore admits to a history of violence toward those who don't fit in; the FBI arrives and turns to the sheriff's role in the crime; Trena's fight for justice seems ever more elusive; the town begins to pay a different kind of price.
