Two aeroplanes collide over Oakland, while in the distant future an elite commando unit of time travellers prepares for a terrifying mission. But not everything goes according to plan...
At the site of the greatest disaster in the history of American aviation, investigator Bill Smith reaches ever more astonishing conclusions, especially when he finds an object in the wreckage of one of the aircraft whose origin nobody can explain. Even so, he does not expect that a series of inexplicable incidents will turn his life upside down and bring an end to the world as we know it.
