Harris County, Georgia, 1912. A white man, the beloved nephew of the county sheriff, is shot dead on the porch of a black woman. Days later, the sheriff sanctions the lynching of a black woman and three black men, all of them innocent. In trying to figure out what led to this unthinkable crime, Karen Branan --- the great-granddaughter of that sheriff --- was forced to confront her own deep-rooted beliefs surrounding race and family, a process that came to a head when she learned a shocking truth: she is related not only to the sheriff, but also to one of the four who were murdered.
