The year is 1963, and self-important Byron Watson is the bane of his younger brother Kenny's existence. Constantly in trouble for one thing or another, from straightening his hair into a "conk" to lighting fires to freezing his lips to the mirror of the new family car, Byron finally pushes his family too far. Before this "official juvenile delinquent" can cut school or steal change one more time, Momma and Dad finally make good on their threat to send him to the deep south to spend the summer with his tiny, strict grandmother. Soon the whole family is packed up, ready to make the drive from Flint, Michigan, straight into one of the most chilling moments in America's history: the burning of the Sixteenth Avenue Baptist Church with four little girls inside.
