In the dead of a freezing winter, in small town Maine where nothing ever happens, school bus driver Lesley does her end-of-day check of the bus. In a moment of odd wonder a bluebird flies into the bus, gripping her attention for just seconds. As the unwary bluebird exits, Lesley’s mind has already moved on. Tragically, she has failed to notice a young boy asleep in one of the back row seats. It’s an oversight that has immense implications. The following morning, ready to start her school run, she comes across the boy – he is already in a coma and close to death. The incident, triggered by the intrusion of a tiny glitch in the fabric of mundane life, spirals the small ‘ordinary’ town into an emotional storm of blame, guilt and heartbreaking confrontation.
