Where James is passive, Michelle is anything but. And she quickly discovers that the flashing green light is actually a button. Which she presses. Which may or may not unwittingly break the rules of the universe at least as those rules apply to Hartsfield-Jackson Atlanta.

Before they can figure up from down, strange, impossible things start happening- snowstorms form inside the B terminal; jungles sprout up in the C terminal; and earthquakes split the ground apart in between. And no matter how hard they try, it seems no one can find a way in or out of the airport. James and Michelle team up to find their families and either escape the airport, or put an end to its chaos–before it’s too late.
