When University of Michigan sophomore Celeste Tyree travels to Mississippi to volunteer her efforts in Freedom Summer, she’s assigned to help register voters in the small town of Pineyville, a place best known for a notorious lynching that occurred only a few years earlier. As the long, hot summer unfolds, Celeste befriends several members of the community, but there are also those who are threatened by her and the change that her presence in the South represents.
