Caroline, now a successful knitwear designer, spends her time flying between her business in England and her lover in Italy. As far as she's concerned, her school days, and what happened to her the year she left, should stay in the past. Eleanor, meanwhile, is unrecognisable from the fun-loving girl she was in school. With a son who is barely speaking to her, and a husband keeping a secret from her, revisiting the past is the last thing on her mind. But when an unexpected letter arrives for Caroline in the weeks before the reunion, memories are stirred. Will the sisters find the courage to return to the town where they grew up and face what they've been running from all these years?
