On the island of Martha's Vineyard in the 1950s there exists a proud, insular, nearly unassailable community known as the Oval, made up of the best and brightest of New York's and Boston's black bourgeoisie. Dr. Clark Coles and his wife Corinne, pillars of this community, are mortified that their youngest daughter Shelby is set on marrying Meade Wyler, a white jazz musician from New York. Equally alarmed is Lute McNeil, a successful black furniture maker from Boston who is new to Oak Bluffs and desperate for social acceptance. Lute has fallen in love with Shelby Coles, or at least the way of life she represents, and he will stop at nothing to pull her away from Meade. As the day of the wedding approaches, the tension surrounding Shelby, Lute, and Meade builds, climaxing in a single tragic act that will forever change the lives of three American families.
