During a terrifying storm, Air France flight 006 - inexplicably - duplicates.
For every passenger, there are now two: a double with the same mind, body and memories.
Only one thing sets them apart - while one plane lands in March, the other doesn't arrive until June.
Nothing can explain this unprecedented event. But for each duplicated passenger, an impossible moment of reckoning awaits.
If there are two of you, and just one life . . . who gets to live it?
