It’s Christmas Eve at JFK in NYC.
Charlotte is a British student, waiting for a flight home after the worst semester of her life. Anthony is a native New Yorker, surprising his girlfriend at the airport after three months apart. Charlotte has just been dumped, and Anthony is about to be dumped, right in the middle of the holiday crowd.
Charlotte’s flight is canceled when a blizzard blows in, and Anthony can’t bear to go home. So, they set out into the city together, clutching a book Charlotte picks up in the airport gift shop: Ten Easy Steps for Getting Over Your Ex. For this one night, they’ll focus on healing their broken hearts ... together.
Step-by-step, the two struggle to put the past behind them. But the snow is so enchanting, and the holiday lights are so beguiling, that soon their shared misery gives way to something else. Soon, they’re not only over their exes — they’re falling for each other.
Then a subway ride splits them up by mistake. Will they reunite before Charlotte’s flight leaves New York forever?
