A year after the crash, still gripped by an almost paralysing grief, Joe encounters a woman who claims to have survived the crash. But before he can ask any questions, she slips away. As desperate chase and shattering emotional odyssey will lead Joe to a truth that will force him to reassess everything he thought he knew about life and death - a truth that, given the chance, will rock the world and redefine the destiny of humanity.
