Jane Austen's best loved characters return to our screens six years after 'Pride and Prejudice' ends. It is the eve of the Darcys' annual Lady Anne ball at their magnificent Pemberley home. Darcy and Elizabeth are relaxing with their guests after supper when the festivities are brought to an abrupt halt. A scream calls them to the window and a hysterical Lydia Bennet tumbles out of a carriage screaming murder. What follows is the sombre discovery of a dead man in Pemberley woods, a brother accused of murder, and the beginning of a nightmare which will threaten to engulf Pemberley and all the Darcys hold dear.
