When Dr. Ruth Whitehead meets graduate student Carmelita Robertson, who had come to do research at the Museum of Natural History in Halifax, the women realize both their ancestors come from South Carolina, and that their names sound shudderingly familiar. Embarking on a journey to Charleston in search of their connection, Ruth and Carmelita encounter a modern South where the Klan is on trial for burning black churches and where they must come to terms with the thunderous cruelty of the past.
