One day, all of the white people in America walk into the nearest body of water. A year later, Charlie Brunton is a Black man living in an entirely new world. Having served time in prison for a wrongful conviction, he’s now a professor of electric and solar power systems at Howard University when he receives a call from his 19-year-old daughter, Sidney, who was left behind by her white mother and stepfamily. Traumatized by the event and terrified of the outside world, Sidney has spent a year in isolation in Wisconsin. Desperate for help, she turns to the father she never met, a man she has always resented. Sidney and Charlie meet for the first time as they embark on a journey across a truly “post-racial” America in search of answers. But neither of them are prepared for this new world and how they see themselves in it.
