Daren Renard is an FBI agent with a questionable track record that has earned him the confidence of his superiors. He is sent to Charleston, South Carolina to investigate the lynching of a fifteen-year-old boy after the resulting unrest leads to the murder of a deputy sheriff. To aid in his investigation, he recruits Andrea Watts, a local detective and single mother, who helps him to pull back the curtain on the city's legacy of racism, secret societies, police corruption, and generational trauma.
