Two rival musicians, Lindsay and Wes, who perform in a dueling piano show, suddenly find themselves without a gig on Christmas Eve and decide to road trip to their neighboring hometowns together. During the drive, the mismatched pair find themselves surrounded by Santa conventioneers, saving a Christmas nativity play, performing onstage in Nashville with music royalty, and braving a massive snowstorm which just may lead them to making sweet music together.
