Grania's mother, who knows the history of the last hundred years, watches in horror as her daughter's life and Aurora's life from the neighboring manor house intertwine. Will history repeat itself? What is the woman afraid of? What fateful tragedies did the Ryan family have to go through, and what awaits the new generation?
