Known as the town bully, Ken Rex McElroy terrorized tiny Skidmore, Mo. for decades. On July 10, 1981, the town had enough and 60 people surrounded his pickup truck and shot him dead on Main Street -- but no one claimed to see a thing.

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.
