Against the historical backdrop of the French expedition in 1840 to retrieve Napoleon's body from Saint Helena, two men and a woman find themselves engulfed in long-dormant and dangerous political passions.

Philippe de Rohan-Chabot, an aristocratic young diplomat, is charged with bringing the body from the island prison where Napoleon died to a glorious tomb at Les Invalides in Paris. Chabot's rival is the aging diplomat and author Henri Beyle, known to posterity as Stendhal. The enigmatic and impulsive Amelia Curial must free herself from the shadow of her mother's scandalous loves and untimely death, and from the life of stale convention that her family urges upon her. The dead emperor is a token in a political game to appease the enemies of the monarchy, but that gamble imperils the king's rule and a new revolution looms. Meanwhile, the interplay of the three central characters traces a delicate pattern of romance, longing, misunderstanding, and the obstacles to the pursuit of happiness.
