She thought being stranded was the worst thing that could happen. She was wrong.
Mira needs to get home for the holidays. Badly. But when an incoming blizzard results in a canceled connecting flight, it looks like she might get stuck at the airport indefinitely.
And then Harper, Mira's glamorous seatmate from her initial flight, offers her a ride. Harper and her three friends can drop Mira off on their way home. But as they set off, Mira realizes fellow travelers are all total strangers. And every one of them is hiding something.
