It is 1945 and Anne Shirley now a successful, middle-aged writer has returned to Prince Edward Island for an extended visit. A long-hidden secret in the form of a letter from her errant father is discovered under the floorboards at Green Gables. Anne delves into long-buried memories, reliving the troubled years before she arrived as an orphan at the Green Gables farmhouse. She is forced to confront the fact that she made up stories about her life; after her mother died and when her father deserted his young daughter. Over the course of one remarkable summer, Anne Shirley discovers the astonishing truth about her father, the origins of her quest for 'kindred spirits' and the roots of her brilliant, magical imagination.
