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.

Ken Rex's widow, Trena, comes forward with eyewitness testimony but investigators derail her at every turn. Rex's background and controversial relationships come to light. A brewing federal investigation threatens Skidmore's secret.

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.

20 years later, two shocking crimes rattle Skidmore's next generation. Wendy Gillenwater is beaten to death, Branson Perry vanishes from his home -- both in broad daylight. Rumors swirl, but as usual, no one seems to know a thing.
