In the year 1183, on the occasion of the Christmas holidays, the aging King Henry II of England must designate the heir to the dynasty. For this event, the king's wife, Eleanor of Aquitaine, who had spent ten years in prison for participating in a plot against the monarch, are brought; the king's mistress, the vain Princess Alix; his brother, the King of France Philip Augustus; and three of Henry II's sons: Richard the Lionheart, Geoffrey, and John (later called Landless). All the members of the family hate each other fiercely and are bound only by an extraordinary thirst for power, while they are ready to commit any treason for it.
