When Melbourne lawyer Nathan Smithson takes on the case of mad, wealthy Edward Fonçeca's inheritance trial against his ruthless brother in 1902, he must unearth long-buried family secrets to have any chance of winning. Brazil, 1852: François, the Count de Castelnau and French Consul to Bahia falls dangerously ill on a naturalist expedition and is delivered by a rainforest tribesman to the Fonçeca household. Carolina Fonçeca is 16 years old and longing to leave the confines of her family's remote Brazilian sugar plantation. With a head full of Balzac and dreams of Parisian life, she is instantly beguiled by the middle-aged Frenchman. What Carolina doesn't know is that François has a wife and son back in France. Desperate for a new life, she makes a decision that will haunt her forever.
