Avery Jennings and Ryan Shaw are both leaving New York on Christmas morning to fly home to Seattle. By chance, they are seated in the same row and strike up a conversation that only complete strangers might be comfortable with. Avery's past is filled with hurt and regret and when she and Ryan meet, she has just ended a relationship with someone she has loved for a very long time. Her attempt at staying friends with her ex leads to bad decisions and awkward situations. Ryan has been single for a while now and she has no intentions of changing that status. If her past has taught her anything, it is that she is much better off alone. Neither of these women are looking for anything serious, but what happens when something sparks between them and it pushes both of them to confront their own fears? Can something completely casual turn into something more?
