On Christmas Eve, ten strangers at the Denver airport are trying to make it home in time for Christmas when a snowstorm sweeps through, grounding all flights. Stuck in the airport together, they help each other discover the magic of in-between places.

Six intertwined stories unfold in the airport as the clock ticks closer to midnight: Landry runs into her ex-girlfriend Resa, and the two women hit it off like nothing ever happened-until things start to get serious. Unaccompanied minor June convinces Adrian to pose as her boyfriend for social media that evening, but what happens when she wants to stop pretending? Charles is struggling during the first holiday season since his wife's death, and the resulting tension with his daughter only makes the night more difficult. Wes and Keely had hoped to forget about their fight during the holidays, but being stranded at the airport brings emotions to a boiling point. Airport employees Trevor and Kat have been best friends since middle school, but can Trevor work up the courage to tell Kat he wants to be more than that? Through it all, heartbroken Mariel is determined to end the worst year of her life on a good note, and ropes everyone into her scheme to make it happen.
