Roxanne Reeves defines her life by the committees she heads and the social status she cultivates. But she is keeping secrets that make her an outsider in her own town, always in search of acceptance. And when she's given a job none of the other white women want - researching the town's African-American history for a tour of local sites - she feels she can't say no. And elderly Grace Clark, a retired black schoolteacher, agrees to become her guide.
