Charleston, 1964. Ida Trueluck is still adjusting to life on her own. Moving into her son's house creates a few family conflicts, but the widow's saving grace is her whipsmart granddaughter Trudy. Ida makes it her top priority to give the girl a summer she'll never forget. When a runaway truck nearly takes her life, Trudy makes fast friends with the boy who saves her. But since Paris is black, the racism they encounter inspires Trudy's surprising summer mission: to take down the Confederate flag from the South Carolina Statehouse. And she knows she can't do it without the help of her beloved grandmother. With all of Southern society conspiring against them, can Trudy, Ida, and their friends pull off the impossible?
