An unscheduled aeroplane arrives on the tarmac at a small Midwestern airport. All attempts to reach those onboard fail. Only when an official boards the plane is the reason for this clear...it is full of babies.
The mystery of this flight remains for over a decade. Until adopted kids Jonah, Katherine and Chip start to question their roots. Strange that a person can be missing and not even realise it. Shortly after this the letters begin: "You are one of the missing"; "Beware! They are coming back to get you."
