Sitting alone, overlooking the still and blue lagoon, Ana Magdalena Bach surveys the men of the hotel bar. She is happily married and has no reason to escape the world she has made with her husband and children. And yet, every August, she travels here to the island where her mother is buried, and for one night takes a new lover. Amid sultry days and tropical downpours, lotharios and conmen, Ana journeys further each year into the hinterland of her desire, and the fear that sits quietly at her heart.
