On a crystal clear Mediterranean day, Briony McAllister sits playing with her four-year-old daughter, Katie, while she waits for her mother, Valerie, to join them. Valerie has recently moved to a picturesque town in southern Spain to finally leave behind her turbulent past and find a peace that has always eluded her. Briony has no idea that in a few moments time, her relationship with her mother will change irrevocably. As Katie plays, Briony pulls from her bag an old photo album, found in a box in her mother's new home. As she begins to study the faded photos, a letter falls to the ground.
