How much does chance play in our lives? Why do we find ourselves in situations that we should have avoided? What gives some people a better chance than others? When circumstances collide, what happens to chance? When Alex Langley vanishes, what chance do the Police and his family have to find him? When a man is brought in to emergency with life threatening injuries, what chance do the surgeons have to keep him alive? When he's had massive head injuries, when he's been in a coma for weeks, when the doctors think he might be brain dead... but he can still hear them, what chance does he have? What is it like to be a prisoner who can't communicate? What will happen when the doctors need a heart, and they want to take his? When a choice has to be made, what chance does Alex Langley have? Can they take a heart without asking?
