On the death of the celebrated photographer Max Hollingbourne, his daughter, Ruthie, returns to his villa in Greece after 15 years in exile. The youngest and estranged member of a once close-knit London family, Ruthie is haunted by a dark secret from her childhood, one that fractured her family and drove her mother to madness. Still, following her father’s death, she and her older sister, Vinny, manage to build a fragile happiness at the villa where they had spent their summers as girls. But the arrival of an English family at a neighboring cottage, and the presence of one young girl in particular, trigger a chain of events that will plunge both women back into their harrowing pasts with shocking and fatal consequences.
