James and Michelle find themselves in the Atlanta airport on a layover. They couldn't be more different, but seemingly interminable delays draw them both to a mysterious flashing green light and each other.
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.
