“No One Saw a Thing” (August 1, Sundance)

This six-part series, produced in part by Blumhouse TV, follows the aftermath of a 1981 shooting in Skidmore, Missouri that many believe was an act of collective vigilantism. Over the course of the show, the series investigates the town’s history and the many theories as to why no one who witnessed Ken Rex McElroy’s death was willing to testify to who may have been responsible.
