New York City
Jocasta follows a wealthy heiress of a plantation fortune, a haughty member of the social elite of nineteenth century Martinique, and a woman who is heedless of what the gossip-mongers say about her. Catherine de la Célianne exemplifies a willfulness alien to the stratified, biracial colonial society she inhabits. Suddenly, as word spreads of her mysterious night visitor, Catherine is engulfed in the aftermath of a youthful indiscretion long ago. One by one, a series of small revelations threaten to destroy her.
