Ten years ago, Bella Soroush's life was ruined by one of her pupils - Kane McCarthy. She has gradually rebuilt things - new school, new town, new friends - and finally feels at home in the depths of the countryside. Now Kane is back in her classroom, armed with relics of the past and claiming to want forgiveness. As the truths they've clung to begin to collapse, teacher and pupil are forced to confront their prejudices and the shared history that has bound them together.
